system is sluggish. geekbench4 CPU score of 4xx (single) and 8xx (multi)

[mrjayviper]

setup is intel s2600CP2 + 2x Xeon E5-2650L (8 cores/16 logical cores) + 64GB

----------

Looking at CPU history (Activity Monitor), I can see 32 logical CPUs (inclusive of hyperthreading) but only 2 is active.

 

If you look at this screen of CPU history taken on my 2017 MBP, you can see activity in all logical cores (see below). In my Hack, only the top 2 cores shows activity.

 

I haven't messed around with SSDT yet (via ssdt generator from Piker as I'm having issues with that).

 

I did try using the SSDT for E5-2650 from rampage dev and it didn't make any difference to number of cores being used.

 

Any ideas on how to fix this? Or at least point me to the right direction? Thanks
