- kuschku 9y agoThis patch is part of a patchset that isn’t merged yet. The patchset adds 29% (with PCID) or > 50% (without PCID) overhead to syscalls on Intel processors. Overall, this has between 0.28% (best case application with barely any syscalls) and > 50% (du, which does lots of syscalls) impact on performance on Intel processors.
- amluto 9y agoPTI has been merged.
- kuschku 9y agoBut it’s not been released yet, right?
- DSMan195276 9y agoIt's in the current release candidate, so on track to be in the next release in a few weeks.
- daenney 9y ago> Nothing will happen since this patch will speed up AMD hardware, but leave Intel the same as before. It doesn't speed up AMD hardware. Intel incurs a performance penalty (so it doesn't leave Intel the same as before), but that penalty doesn't make your AMD CPU magically go faster.
