I don't get hdrhistogram at all. It's really just histogram with a shitload of logarithmic buckets.

- sbanach 8y agoThe compression format is really smart, there's a neat trick to make the logarithm calculation fast, and there's a concurrent thread handoff mechanism so you can swap out a histogram without disturbing the thread you're measuring (though last two probably only in the java version). Those three make it super useful for very low impact performance measurements.
