VMs becoming very slow after upgrading from vCenter 6.0 to 6.5 and ESXi 6.0 to 6.5

Hello team,

We recently upgraded from vCenter 6.0 to 6.5 and ESXi 6.0 to 6.5. The upgrade went okay, however all my VMs have become very slow since the upgrade. These slowness of VMs is having negative performance on my Virtual infrastructure and users alike. We have upgraded the latest firmware both on the Hosts' BIOS and NICs, yet the problem remain unresolved.

Please help!!!

Regards

Moderator note: This is not a VCP question, thread moved to the ESXi product area.

what exactly is slow? Is it: CPU, Memory, Networking, Storage... or a combination of all those? Take a look at esxtop to figure out what is causing the problem. Any limits set on a VM level? Resource Pools? So many things could be going on here. More info would be needed to provide any help.
