Thanks a bunch. Don't think I'll worry about it either. Sure I wanna find primes and compete. I guess I'm just not as competitive as some. All good tough, each to their own :)

Ok n00b question, I searched around and while I've seen a few references to it, I've not seen what is bunkering. I take it since I don't even know I'm already behind according to previous posts but hey, better to be behind than not in the race at all =)

If the system is solely dedicated to running PG and doing nothing else (say, being used as a daily driver), then turning HT in BIOS is generally better for LLR performance. And if so, set usage to 100%. Alternatively, if you cannot disable HT for whatever reason, then set usage to 50% to mitigate the effects of leaving it on.

Outside of that, the usual applies: try to keep all your work inside L3 cache to boost performance, and assuming you're talking about that E5-2697 v2, remember that it doesn't have AVX2 and thus will be way lesse efficient than more modern machines.


Hey, thanks a bunch. Also, thank you for saying kindly that my old Dell is, well old haha. I'll make said changes once my cache dries up.

Ok, so for setting up my dell server (24-core, HT enabled) for LLRI should either turn off HT in the BIOS or tell PG to only use 24 cores? I ask since in preferences it is suggested to enable HT which it already was, and set my core count to 48. As such the system is only running about 45% loaded. While the answer would seem self-evident, I've been working on this project for all of a couple days and am not sure how to optimize my CPU crunching.
