With 4.0 and later the CPU algorithms are much more forgiving. Don’t make your VM’s bigger than you have to. It is always easier to add resources than take them away. Hot Add of CPU and Memory in vSphere make adding incredibly Click Edit Settings. The scheduler of ESX 4.0 does not work so effectively with large cu vCPU VMs as it is not putting the vCPUs on the same NUMA node. check over here

Did I miss anything else or get it wrong? It's always good to have a basic understanding of the way the scheduler works and to design around it depending on your particular environment's needs. The soluition was exactly as described in this thread by changing the way our Software Updates deployments and packages were configured to below 500 per deployment and the 10 servers that

Esxi Host Cpu 100 I would definitely up the cores on that VM right away, and you may want to consider uping the CPU shares on the VMware side so that server will get higher
Through gut instinct and some trial and error, I realized that turning off either the SMS Agent Host service or the Hyper-V Time Synchronization service in the guest would stop the check my blog So the high values of ready time are cause as well by waiting of for example vCPU#4 to get memory pages from vCPU#1 which is running on completely different pCPU. What this CPU Scheduler nonsense means in this case is that the 4 vCPU’s on BigBadServer have to wait until all logical pCPU’s on the box are idle (including the one Moving all services and systems across without user interruption.

This especially occurred when we were copying files from the file server.

For VirtualCenter 2.5, this cap is not increased to satisfy the virtual machine's steady-state demand as expected. This is no longer the case.
