Dear all,

Hope all of you are safe during the pandemic,

I have been struggling to solve a very slow vps in a 10vps hardware node running virtualizer with no luck so far.

Hardware Node

Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz ( 2 sockets) - I am thinking this is 6 cores per CPU, with 2 threads per core and 2 sockets so a total of 24 virtual CPUS?

Disk set up on Hardware Node:

1. 2x 4TB  ( VPS Storage )
2. 1x 1TB SATA ( OS Drive )
3. 960GB SSD. ( Used as Backup )

VPS v1001 is able to see the following CPU topology.
