After years of repeatedly struggling with vtune installs in cloud environments just to get a few specific hw metrics only to fall back on manually building some perf stat events fr…

Despite flamegraphs being very intuitive I still have people ask me, what do I look at? Instead of explaining my usual cmd+f's over an over I made a tool which can annotate flamegr…

better than transparent?

I'm conflicted about this one. march native definitely. Have you seen substantial gains from omitting frame pointers?

lol never knew about this thanks. Has this actually slowed down someone's code?

also less logging. Seen this pop up way too many times

I'm curious what backpocket optimizations you have from your past experiences which you pull out when a workload costs too much in the cloud. For me its. * disable lower c-states *…

I like the idea. Small nit: the scrolling is a little unintuitive.

I have found that many companies don’t have time for performance engineering and leave random tunables incorrectly configured for their workload. Instead of solving the same proble…

I wonder how effectively it can utilize all of its execution units for common workloads. Frontend boundedness is often a big issue especially with jit
