On a related note, also try disabling mitigations... if that's actually a relevant thing to do (somewhat out of the loop - maybe they're off by default or maybe the overhead is minimal now, not sure).
- nsajko 5y agoDisabling mitigations could improve performance, but I'm not sure whether it would change how the performance distribution looks. So, in my experience the distribution is a finite set of pulses, equivalently, the performance largely falls into some predefined level, where the fastest/best performance level is usually the most likely, and the levels roughly get less likely the worse/slower they are. So what I'm saying is that disabling hw-vuln may make all performance levels faster, but I doubt it would eliminate many of them. I'll for sure play around with that some day, though.
