Since both CPU and memory are not bottleneck, the problem should be at Disk side.īecause it is not possible to repace new hard driver, I wonder if there is some guide for Vmware player performance tunning, especially for hard driver?īut the tools vmware-vdiskmanager in the link does not exist in my side. CPU usage keeps about 12%, and only 300M~ memory are really used. For ACE TAO compilation, it takes 2 days in hosted XP but only less 3 hours in Ubuntu. I allocated (3G,2 core for 15G) for VMware player.įor example, for Boost, the bootstrap.bat takes about 3 hours to complete in XP while it is only several seconds in ubuntu. The installed OS is Ubuntu 12.04 and then I installed vmware player, where the hosted OS is XP. My machine is T410(i7 620, 6G memory and 5400 harddriver). I find I was unable to tolerate the performance. Then you can investigate further to see whether it is the shared storage, network, physical CPU, or a physical RAM problem.I did some compilation (ACE TAO, and Boost C++ library) in vmware player virtualmachine environment. One recommendation here is to isolate the problems and see whether it is the VM itself or the physical ESXi first. In this post, we gave you a few paths to explore, but we have just scratched the surface. Troubleshooting a performance problem is a job in and of itself. Check to make sure the firmware of your HBAs is up to date.When running the same guest operating system in both virtual machines with the same amount of. Make sure that you have the latest BIOS on your physical hosts. VMware Workstation Player also has excellent performance.Your host bus adapters (HBAs) are on VMware HCL and are certified for ESXi.If you identify a storming-related problem, you can also verify that: You can also reduce the number of VMs per LUN if you're not using VMware vSAN, which is not relevant for this situation. You can easily test it if you migrate your VMs to different, more performant storage, attached to the same host. Volumes created on top of spinning medias were slow, unreliable, and take a long time to rebuild if any of the underlying hard drives failed. Spinning media often caused poor performance in virtualization infrastructures. While the newest virtual infrastructure deployments get the best of the best, all-flash storage, an old infrastructure might still be using spinning storage. If you see only values of zero, as in our case, then your ESXi has still enough physical memory, and this memory reclaiming technique has not been used (yet).Ĭheck the MCTLSZ value for memory ballooning statistics Slow storage ^ Then look at the MCTLSZ value, which shows the amount of guest physical memory that was reclaimed (if any) by the balloon driver. On the main screen, type m for memory, then type f for fields and select the letter J (memory ballooning statistics). This is often the case when the physical memory of the host is fully utilized, and you have actually configured more memory for your VMs (overcommit).Īgain, we can use the esxtop command here and check the value. We can also check whether ESXi is struggling from a memory standpoint and reclaiming some memory from VMs. #VMWARE WORKSTATION PLAYER 7 PERFORMANCE TUNING FREE#Finally, you can move some VMs to other hosts to free resources. If there is no limit configuration on the VM, then the load is too high and the only thing you can do is either increase the physical CPU number on the host (if possible) or reduce the number of virtual CPUs within each VM. The CPU limit can be set on the per-VM level or at the resource pool level (if used). Make sure the VM is not configured with a CPU limit that is a limiting factor. This value should stay under 5% under normal workloads. This gives you an idea of how long (in percentage) the VM was ready but could not be scheduled to run on a physical CPU. If your ESXi has a CPU overload, you can connect via an SSH client such as Putty and initiate an esxtop command to verify the %READY field. Clear the Connect At Power On Checkbox Check CPU overload and CPU limit ^
