Programs such as Photoshop, Final Cut Pro and Chrome use a lot of memory. Kill Memory-Hungry ProcessesĪpplications tend to run slowly when there is not enough memory space available. Now that we know the reasons behind a slow Mac (macOS Monterey), the next thing we need to do is optimize it according to these possible reasons.

Then you can investigate further to see whether it is the shared storage, network, physical CPU, or a physical RAM problem.Also Read: Mac Won't Connect to Wi-Fi? Here's How to Fix It Why Is Your Mac Slow After Upgrading to macOS Monterey?īefore we introduce you to ways to speed up macOS Monterey, let's take a look at why your Mac is slow. 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.Make sure that you have the latest BIOS on your physical hosts.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.

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.
