comment Major slowness in 1% of nginx responses under load
@parkamark Yes, thank you, that was the first thing I tried. Didn't help. The effect stayed.

comment Major slowness in 1% of nginx responses under load
Sure, the result, of course, differs based on that. The less concurrency (-c) - the less chance of this random behavior and it is less severe. But, anyways, it seems really weird. A lot of near zero response times and very slow 1% responses. It seems like it should be "everything is slightly slower", not "just 1% of very-very slow ones". So, I hoping for some kind of pointer on how to hunt for this thing.

comment Major slowness in 1% of nginx responses under load
@AndrewHenle I tried most of the sysctl recommendations that I have googled, I compiled golang's http server (and see the same result). I tried it on DigitalOcean and on Dedicated servers and in OpenVZ containers. I tried a lot of recipes that help tuning nginx params. Frankly, a lot of random movements found by googling stuff. But none of those help. That's where I decided that probably StackOverflow's brain is the last point of hope for solution.
