With 30.3b3 (but also with Version 29), I get really bad multi core scaling on an Intel i59500:

Yes. So it is a severe memory bottleneck? It's a work machine we are preparing for delivery. Beforehand, we always run some tests. I'll bring that up at work, since our software (which shall be running on that machine) is also vectorizationaware and will be limited by that, too, I guess (of course much less than the highlyoptimized gwnumcode).

Viliam, how did you go about parsing results.bench? I'm trying to do this in excel on about 4,500 records but I assume there has to be an easier way to do this as I'm not finding a single clean delimiter. Does P95 provide a parsed benchmark output file that I'm overlooking?

I have done it the hard way... I have copied them manually into the spreadsheet, one by one.
If you want, you can send me the rows by email and I will write some quick Python code to put them in usable .csv format, and then I will send you back a spreadsheet.

Well not exactly, I found enough unique delimiters to parse the data in stages. All I need to do now is load it into a statistical analysis tool and see what it tells me. That said, based on a cursory review, I'm fairly confident that 1  8 core worker is optimal for this i99900KF. Thanks again!

Well, assuming I'm looking at these benchmark results through an appropriate lens, it appears that 1 worker is (on average) a ~24% improvement over the next best alternative of 2 workers and HT carries a ~13% throughput penalty for this i99900KF.

Finally getting around to setting up my 10900X system. RAM is 3200C16. Benchmark below is stock. I played around with various OCs and as expected they don't make any difference in throughput (but a lot in temperature!)the stock speed with AVX512 (apparently 3.4GHz) easily saturates memory bandwidth.
