With most LLR, performance of my 2080Ti is affected by how many cores are running LLR. The following times are for PPS sieve while running GCW:

7 cores - 4 minutes, 16 seconds
6 cores - 3 minutes, 44 seconds
5 cores - 3 minutes, 8 seconds
4 cores - 2 minutes, 25 seconds
3 cores - 1 minute, 44 seconds
2 cores - 1 minute, 27 seconds
1 core - 1 minute, 22 seconds
0 cores - 1 minute, 23 seconds

I'd love to double check the time for 1 core, but boinc manager is now sulking and won't let me run PPS sieve. I may have to reset it.

My box is a 9900K with a 2070 and PPS Sieve clearly needs to use the most CPU to service itself... something like half a core. AP27 is by far the lowest CPU hog. GFN is between them but I've only been running the huge GFN work so I suppose the CPU usage could change for the smaller GFN's. I am of course talking about the GPU versions of those 3 subprojects.

I have made some more measurements, this time ESP with GFN16 (ESP is running single threaded).
The following are the times for GFN16:

7 cores - 1 minute, 23 seconds
6 cores - 1 minute, 24 seconds
5 cores - 1 minute, 22 seconds
4 cores - 1 minute, 16 seconds
3 cores - 1 minute, 6 seconds
2 cores - 1 minute, 2 seconds
1 core - 1 minute
0 cores - 1 minute

Cheers, Nick
