Some optimal thread counts for an i5-8400 CPU.




PPS DIV - 2 threads x 3 tasks seems optimal for this subproject

SGS - 1 thread 5 tasks using only 5 of 6 CPU's provides faster individual run times as well as faster overall throughput.

321 - Use all 6 threads for best runtimes




Keith may be able to help with a few more.

Quick top tip for those of us new to or setting up app_config for the first time: make sure it goes in the C:\ProgramData\BOINC\projects\www.primegrid.com folder, not just C:\ProgramData\BOINC. Now cooking on gas here with fresh app_config, first time set-up on this Windows image!
