VMware released a update 22.05.2013 (ESXi510-201305001) which by the looks of it will lower performance by default.
My question is by how much...?
What kind of Virtual Machine workload usually benefits from Intel VT Flexpriority?
Since we as of yet have not been affected by a PSOD as mentioned in the KB:VMware KB: VMware ESXi 5.1, Patch ESXi510-201305401-BG: Updates esx-base
We are considering installing the update, but re-enabling flexpriority.
I can't find much documentation about where and when flexpriority is usefull for virtual machines except it seems to only affect 32 bit VM's?
Has anyone actually been affected by this bug? If you have, could you share your hardware information?
