VMware Tools is a suite of utilities that enhances the performance of the virtual machine's guest operating system for supported guest operating systems and improves management of the virtual machine. In VMware Workstation 11 which will be available in has been available since December, for graphics-intensive applications, 2GB of video memory can now be allocated for additional workload processing power. VMware Workstation 15 and later supports virtual graphics memory up to 3GB.
To echo the poster above. In my experience: Hard Drive speed is the primary performance factor of desktop based VMs. Just switching from a RPM drive can have a massive impact on performance. Enable shared folders in your VM config so you can pass files back and forth and store large stuff outside of your VM. That way the VM isn't trying to manage that space. Always remember VMs run best when optimized for performance.

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. By saving your virtual machine state, you eliminate the need to launch the machine from scratch, which is a slow process and requires a significant amount of power and resources.
Saving the state of your VM is similar to using the hibernate or suspend utility when shutting your physical device down. VM program speeds vary between users. This difference in how a VM program performs is because VM performance is heavily dependent on system configurations, host OS, guest OS, and other factors. If your VM program is failing to deliver the performance levels you need, consider switching to a different VM program.
VMAN provides a wide range of powerful capabilities, including a VMware capacity planner tool to help companies accurately predict CPU, storage, memory, and network requirements. How does it work? With this tool, you can model upcoming server and hardware investments to assess if your existing environment can scale effectively and satisfy requirements. VMAN makes identifying consumption trends easy, allowing you to determine resource warnings and outage dates.
I find this tool is also highly customizable and allows you to create custom sample timeframes, so you can generate tailored capacity plans that account for peak and non-peak virtual machine usage.
Of course, every effective monitoring tool depends on a robust alerting system. You can leverage these data insights to detect and troubleshoot performance problems as quickly as possible. PerfStack can compare and analyze metrics across multiple products simultaneously to create a visual, historical timeline.
AppStack shows monitored nodes in a custom map, allowing you to review virtual machine statuses at a glance. VMAN is a user-friendly solution designed to help you optimize your VM performance, with recommendations for performance tuning.
This tool was created to suit companies of all sizes, is able to scale with your company as it grows, and features a dynamic, intuitive interface.
The graphical representations provided by this tool give you immediate insight into your VM health and performance. To reduce the likelihood of VMware virtual machine issues occurring, and to keep VM performance optimized, it is important for your business to leverage a suitable VMware performance monitoring tool. With the right VMware performance monitoring and tuning tool, you can gain invaluable insights into your virtual environment, informing your tuning activities and helping you establish an ongoing VMware virtual machine optimization strategy.
VMware optimization is a frustrating and time-consuming process, made significantly easier by the right VMware monitoring tool.
If you work on tuning VMware, you will especially like VMAN features such as: Capacity planner tool for detailed CPU, memory, and storage requirements A tool to measure hardware resource utilization, identify critical hardware usage moments, and alert on abnormal resource usage by virtual machines Recommendations for performance tuning of every size organization to help you find where you can improve performance by optimization in your VMware environment You can access a day free trial of SolarWinds VMAN here.
