Remember to use Affinity Watcher if you are on Windows and using Ryzen's and lock each task to a 32MB cache block. PSP tasks use 20MB+ of cache per task. If you run 1 task per CCX with 16MB it will overflow it. So best to lock it to one CCD which is 2 CCX's. This is on the 3000 series.
For those of you running the 5000 series, each CCD is now as big as 2 CCX's were before and you should still lock it to a CCD but the difference is that there won't be cross talking between CCX's in that CCD slowing things down.
Think of CCD's as factories, and the CCX's the rooms with the cores inside the factories. Cache use being project size. If you have to keep moving stuff between rooms or between factories for each project it slows things down. Same idea here.
The 5000 series just has larger rooms with more machines/cores. Cache being the workspace.
For Intel Chips.. cache is a big issue. If you happen to have an AVX-512 compatible CPU you will see some very fast times. If you know your CPU has less than 20MB of cache full MT using all cores is the best way to run it.

From recent testing and running of Universe@home tasks it would appear that running them on same class processors under Linux instead of Windows cuts run times almost in half.
I was seeing run times on 3000 series Ryzens of about 2.5hrs under Windows for the bhspin app. And while running them on the same processors under Linux those times were just over 1hr.
Lesson to be learned here is to run Universe on your Linux Machines and double your throughput over Windows Hosts. Save the Windows machine's CPU cores for something where you won't be running it at half speed compared to under Linux.

ESP Challenge Begins This Saturday.
CPU only challenge. Get your machines ready to rock and roll. :) Benchmarking and testing on your own hardware for optimal throughput should be done.
