Re: TL;DR get your filty paws offa my high accuracy timers
Profilers for one, accurate timing quite useful there.
The basic attacks work on the principle of measuring latency of access to cache lines, it's not really about the precision of the timer.
Side note, crap timers can be made more accurate, with more iterations.
As an example, I dont have a <30ns timer on this machine, and other stuff is happening, like me waffling on elreg, so if I run my loop, a eleventy-billion times, averaging out the measurements, I will coverage on a very precise measurement.
