That sounds a little slow. One of my systems is nearly identical except the CPU is an older 6700K at 4GHz. It gets 5.5ms on that same exponent range (1 worker). I would expect two workers to be...

It depends on your perspective maybe. At 2.4GHz, 15us is, what, 36,000 ticks? If you re-lock to 2.5GHz you should recover the lost time if you can stay at that frequency for more than 360us....

I had a few Seagate Cheetah 10Ks fail 20 years ago just because I had a loose hot wire flopping around in my case that might periodically short on them. The nerve of those guys selling me drives than...

I suppose this is off-topic but I'm curious--in what usage scenarios would you put a system into hibernate multiple times per day?

Yes, you should always store important data in more than one location. This also includes SSDs. I have had a SSD fail, and I have coworkers who have had SSDs fail. It's very rare, and as you say they...

I don't think anyone is talking about the processor in question running with air cooling.

If you're buying unlocked parts then turbo is irrelevant. For locked parts I guess yes you should expect...

Question is, if the FFT can fit in the combined L2 and L3, is DRAM access going to be the main bottleneck? Or is it going to be limited in that scenario by the efficiency of Skylake's cache mesh...

While I'm certainly not going to buy one it would be interesting to see how prime behaves on it. As we've discussed here previously, a single worker does well on the E5 2699v4 since the whole FFT...

Yeah, this (https://en.wikichip.org/wiki/intel/core_i5/i5-8400#Frequencies) indicates that max freq will drop from 3.9GHz with 4 cores to 3.8GHz with 5/6 cores on that chip. Turbo is dynamic based on...

Yeah that's a good point, the encoding likely is slower when Prime is running. I agree that it really depends on your use cases, and that was my point. I would not encourage someone to just turn off...

If the system is dedicated to Prime95 I would agree. For a system that sees other uses, HT still helps. When I have HT disabled and play a game or encode videos, my ms/iter time in Prime95 goes up by...

That's correct. First of all, it says right on AWS's marketing that the C5 instances support turbo. Turbo and throttling are two sides of the same coin from a logic perspective. Yes unlocked parts...

What does /proc/cpuinfo identify the chip as? I assume it's an 8124M, which means they have an 8S blade where you get two sockets, giving you 72 threads. The most cores currently in a single Xeon die...

Yeah, actually it was a Blu-ray burner, and it had a Ken Burns DVD in it at the time. I think it was just too much burn.

Yes, at least that's how I interpret it. The results don't state the number of cores used per worker, so I would assume it's using 11 cores for 2 workers, 7 for 3, and 5 for 4.
