Here's results of the Nginx benchmark pinned to 1-24 cores: https://docs.google.com/spreadsheets/d/1d_OK_ckLT1zTA_fG4vkq... At 51% reported CPU utilization, it's doing about 80% of…

I'd love to explain, but you'd need to change your name to Brendan first.

Fun data point though, I just ran three data points of the Phoronix nginx benchmark and got these results: - Pinned to 6 cores: 28k QPS - Pinned to 12 cores: 56k QPS - All 24 cores…

Yeah, the obvious thing with processors is to do something similar: (1) Measure MIPS with perf (2) Compare that to max MIPS for your processor Unfortunately, MIPS is too vague sinc…

The advantage of stress-ng is that it's easy to make it run with specific CPU utilization numbers. The tests where I run some number of workers at 100% utilization are interesting …

Some esoteric methods of measuring CPU utilizations are to calculate either the current power usage over the max available power, or the current temperature over the max operating …

Thanks for the feedback. I think you're right, so I changed a bunch of references and updated the description of the processor to 12 core / 24 thread. In some cases, I still think …

A big part of this is that CPU utilization metrics are frequently averaged over a long period of time (like a minute), but if your SLO is 100 ms, what you care about is whether the…

To be fair, in most of these tests hyperthreading did provide a significant benefit (in the general CPU stress test, the hyperthreads increased performance by ~66%). It's just conf…

Expanding on that last point, one of the examples in the article is someone making ~$70 per month in cryptocurrency. The CI people -could- send a lawyer to Vietnam to try to collec…

They're not starting a CI job per hash (that would be too slow). I'm not sure exactly how each of these cryptocurrencies works, but presumably what they're doing is starting a mine…

Investment info sites seem to be skeptical that there's anything wrong with naked shorts. They became illegal after the 2008 crisis, but they're bad in the sense of being extremely…
