I'm testing Ubuntu on 32 Core Xeon with 512GB RAM

wow and how does feel vs a normal PC? I noticed that 32GB doesnt seem to cut it. I do run out of RAM often and crash

I also recently upgraded my machine for image processing.  I went with the latest Intel offering I9 12 Gen.  Some items it processes faster, it depends on if the process can run parallel or needs to run single threaded.  So several processing steps will not make use of all the cores.  The area I found that made the most difference is in memory, I had originally had 32 GIG found I was running out of memory and could not process, so I bumped the machine up to 64 Gig and the software runs very stable even with very large datasets.  I suspect soon, just because, I will bump it to 128 gig of memory.

So while more cores and faster cores were helpful, only too a point, memory is where I found the best results.
