Using virtual machines is convenient and efficient, but sometimes VM performance degrades. Reasons for that vary and may be the result of hardware or software issues.
This blog post explains how to improve virtual machine performance if VM performance is slow on the VMware virtualization platform. Read about the most common issues that cause low virtual machine performance, and find recommendations on how to fix them and improve VM performance.
Insufficient hardware resources are among the most popular reasons for slow VM performance. Also, consider upgrading the hardware of your host machine if you have an old processor with a low number of cores, cache, and low frequency.
At the same time, there must be enough RAM for a host machine. This leads to the degradation of OS and application performance. Moreover, VM performance degrades as well in this case. Always provide the host with enough memory. Read system requirements for your operating system and applications. A Windows Server VM is running on this host machine. That is enough for proper work of both host OS and guest OS without running additional applications that consume resources.
If you provide 6 GB of RAM for a Windows Server VM, the amount of memory for the host machine is not enough, and, as a result, both physical and virtual machines are slow. If you run heavy applications such as databases on virtual machines, adjust VM configuration and add more CPU and memory resources accordingly.
Memory overcommitment is a situation when total resource allocation exceeds capacity. If some VMs are running, but they are lightly loaded, memory is primarily used by the VMs that are heavily loaded because ESXi improves memory utilization.
Memory overcommitment makes sense in test environments. Also, check memory ballooning and configuration of this feature to reclaim unused memory from VMs for efficient utilization of physical memory.
Sometimes, this feature can affect VM performance when the VM needs to use a disk for a swap. CPU overcommitment. VMware provides techniques for rational resource usage, allowing you to provision more virtual processors for VMs than there are physical CPU cores on the host.
If the value is — there should be no reason to worry. If the value is , VM performance degrades. If the CPU overcommitment value is or greater, VM performance is slow, and that may cause many problems. Consider upgrading hardware and adding more RAM to the physical machine on which you run virtual machines. Try to have enough memory to prevent host and guest operating systems from using swap files. Avoid memory overcommitment. On ESXi, run this command in the command line to check whether your server is overloaded:.
Press these keys to change the view: c – CPU metrics is displayed by default , m — memory, n — network, d — disk. Press space to update displayed values the values are updated automatically every 5 seconds. Press h for help and q to quit.
The MEM overcommit avg value is as follows: the ratio of the requested memory to the available memory minus 1. The recommended value of this parameter is 0 or less.
Check running processes and find the one that loads the CPU. Upgrade hardware — install a more powerful CPU or more processors on the host. Check VM configuration. If the number of virtual processors for VMs is more than needed, reduce the number of virtual processors for VMs to free up resources for the host. Low performance of a storage system causes low performance of virtual machines that store virtual disks on this storage system.
Storage latency is critical for VM performance. Hard disk drives with RPM provide extra low performance. Using disks with SAS interface is preferred. In production environments, use non-growable or preallocated thick disks. Eager-zeroed thick provisioned disks are faster for first write operations.
If you use an HDD to store VMs, perform defragmentation of this physical disk drive or array, and perform defragmentation of a virtual disk in virtual machine settings. Use partitions to reduce disk fragmentation. Install an operating system on one partition, store files used by applications for example, a database on another partition.
Update firmware of your HBA on a server. Check disk health. Perform diagnostics of the disk and file system. If the disk is corrupted, replace the disk immediately. Disk encryption reduces performance due to overheads. Move VM files to non-encrypted storage if encryption is not critical for the VM, or turn off disk encryption. Make sure that there is free space on a disk inside a VM.
Insufficient disk space causes performance degrading because an operating system and applications cannot write temporary files. You can migrate your VM to another disk or disk array that is not overloaded. Virtual disk snapshots reduce virtual disk performance. Each snapshot produces an additional delta VMDK file of a virtual disk.
The copy-on-write mechanism is used. As a result, data is read from multiple virtual disk files on the same physical disk, and this reduces VM performance. Disk overload increases as the number of snapshots grows. Snapshots are usually used for temporary purposes for example, when you copy data during a backup job or install or test an application inside a VM.
Delete or commit snapshots as soon as possible. Then reconfigure the VM to use a new virtual disk or create a new VM, and set to use the new consolidated virtual disk. Merge split VMDK files if they are used. Do this on the Windows machine on which VMware Workstation is installed with the command:.
VMware Tools is a set of drivers and utilities used to improve VM performance and user experience. Graphics performance is increased after installing VMware Tools. The mouse is synchronized and works without lags. Check whether VMware Tools are installed. You should use separate ESXi management network , vMotion network , and storage network in vSphere for high performance.
If your existing network bandwidth is not enough to meet requirements, consider a network upgrade. For example, set up 5-Gbit or Gbit network adapters, switches, and routers instead of existing 1-Gbit equipment. Make sure that antivirus software on the host is not scanning virtual disk files as scanning these files can degrade VM performance. Check the health of the operating system running on the host OS and guest OS. Make sure there are no viruses or other malware or ransomware.
This approach allows you to achieve better performance and is rational for large virtual environments. If you use vShield, configure this software properly because incorrect configuration can degrade VM performance.
If you use VMware Workstation This solution will help fix VMware virtual machine slow performance. VM performance monitoring is a widely used method to detect overloads and related performance issues. VM performance monitoring helps you troubleshoot the cause. Remember to monitor VM performance on the host level but not inside a guest OS.
A guest operating system is not aware of virtualization features, such as dynamic resource allocation, and might display incorrect data. VMware provides counters on the host level. These counters provide correct information and are used for VM performance monitoring. Knowing about how performance information is collected inside VMs, VMware developed virtual machine specific counter libraries that allow you to see correct information about VM performance by using the Perfmon utility in Windows guests.
Select these options in two drop-down menus on this page Period and View. Click Utilization in the Monitor tab to see additional information about utilization of virtual machine CPU, virtual machine memory, and guest memory. Similarly, you can select an ESXi host or cluster in vSphere Client and monitor used and available resources in real time and for the selected period.
This blog post explained the main points that require your attention when talking about VM performance issues and recommendations that help improve virtual machine performance.
You should have hardware that provides enough performance, avoid memory overcommitment, and configure software properly. Use VM performance monitoring to detect why VM performance is slow. Disk damage is the most dangerous issue that causes slow VM performance because, in addition to poor virtual machine performance, you can also lose data. To avoid data loss, perform VMware data backup regularly. This software product is the universal data protection solution that supports VMware vSphere 7.

Esxi is a bare metal product so is optimized for guest’s performance. Buyer’s Guide. Download Free Report. Updated: November Esxi from s dry perspective.
But workstation is simpler to work with. Diego Hidalgo. ESXi will almost always outperform Workstation when everything else is created equal. Depends on how ESXi is installed as a type 1 vs type 2 hypervisor Either way the performance will be similar. Regarding performance only It is a very fuzzy question because it is necessary to have more environment info to do a fine recommendation but assuming the basis : the condition you referred – we have to set an identical base hardware – , NO other vm running, the related vm is stored in the SAME physical peripheral and finally the vm has a SERVER role.
The solution is to uninstall version 14 and install version 12 vmware-workstation12 AUR. Please try a cold boot shutting the system down and starting it again.
On systems with librsvg version A workaround is to downgrade librsvg to earlier version, or more preferably, force VMware to use its own shipped version of librsvg :.
As per  the temporary workaround is to downgrade the package libpng to version 1. If the system have installed gcc-libs , that library is already installed. Therefore, it is possible to remove that file and vmplayer will use the one provided by gcc-libs instead. As root do:. Registered bug at Mageia , but it seems that there are no error messages shown in terminal with arch.
Solution is the same, as root do:. An example is the libfontconfig. Check vmware logs in the tmp directory to see which libraries are still not found. Copy them to the appropriate path with libraries existing on the system:. Instead of copying all these files manually, you may want to try exporting an additional setting:. On systems with fontconfig version 2. In such case, it is also necessary to provide a shared object library file libexpat. This applies for at least VMware version To download the tools manually, visit the VMware repository.

In March , with the release of linux 3. When the host CPU frequency changes, the Guest system clock runs too quickly or too slowly, but may also render the whole Guest unbootable. This is likely due to the vmnet module not being loaded . See also the systemd services section for automatic loading. If your mouse’s thumb buttons or other additional buttons do not work, set guest to use advanced mouse. This is related to the current Xorg keyboard layout on Host system.
Keep primary layout e. This issue is related to promiscuous mode which, following standard Linux practice, can only be enabled by the root user. To work around these limitations, the permissions for the networking device in question have to be changed. To uninstall VMware you need the product name either vmware-workstation or vmware-player.

Also, the way snapshots work in the workstation it is better optimized for supporting large amounts of snapshots and switching between them. Switching can be faster in workstation, but it pauses the machines more but ESXi is designed to minimize the downtime and having large snapshots slow down the guest more than workstation does.
If we stick to the initial question: Same VM on different environnement. From purely a performance perspective, ESXi is a better choice. The hypervisor is running directly on the hardware as opposed to running on an existing OS. ESXi has direct access to the hardware without going through a 3rd party so to speak, the performance gains are astounding.
The workstation are for virtualizations pc, ESX virtual infrastructure is to manage its own operating system, have virtualized servers and a centralized administration. ESXi will give you better performance when installed on the same piece of equipment. Usually though, Workstation is installed on consumer-class equipment laptops, desktops, etc. That class of hardware will usually outperform the consumer equivalent hands-down. Like the others said, Workstation is installed on top of an operating system, which has its own overhead and baggage.
ESXi IS the operating system on the hardware, and comes with much less operational overhead. It is a very fuzzy question because it is necessary to have more environment info to do a fine recommendation but assuming the basis : the condition you referred – we have to set an identical base hardware – , NO other vm running, the related vm is stored in the SAME physical peripheral and finally the vm has a SERVER role.
With these conditions the ESXI will always performs better. So my question is what do you need to do with vmware??? However if you plan to deploy a device in a datacenter you may want to use ESXI. I can go into more detail over the telephone if you like. Installing ESXi on that box would mean you would have to have another machine to connect to it via a vsphere Client – you would also need to be on the same subnet so a local switch if you are a small shop could fit the bill.
For anything enterprise related, production workloads I’d recommend going the ESXi route. Mind you this is only the very first baby step towards virtualization and the first building block. Next you could have two ESXi hosts with a shared storage – a local NAS attached to them – if its a lab connect all three objects to the switch and put them on same subnet – install vcenter and viola you have yourself a good environment to spin workload in or experience the true capabilities albeit the starter ones of VMware.
Good luck. NO, Esxi is bare metal hypervisor Virtual layer which sits directly on hardware where as VM workstation needs any operating system to work.
Hence performance of ESXi will be better than workstation. Hence all the production environment usage ESXi. If I may explain in layman terms. VMware Workstation needs an Operating system to run. For a virtual machine to talk to your hardware PC it has to talk to the guest os, then the base OS windows, linux, Mac OS and then to hardware.
There are multiple layers it has to go through before it could execute your guest os instructions. Thats why they call it Type 2 hypervisor.
But when you run a vm on ESXi it uses the hypervisor directly talk to your hardware. Hence it is called Type 1 hypervisor. Unlike the previous scenario there are no multiple layers involved.
