I'm also confused. Disabling all branch prediction would obliterate performance.

- srcmap 9y agoLove to see actual benchmark results from this with various applications - databases, network stack, apache, ngnix, etc.
- apetresc 9y agoPhoronix is doing a ton of very thorough benchmarking for a variety of software. So far just on Intel CPUs but he will surely get to AMD too.
- AstralStorm 9y agoWhat they added is a magic switch that disables indirect prediction across context switch and kernel half of memory space from non privileged cobtext. It is done somewhat as a hack. Overhead on system calls should be relatively low still.
