Benchmarks of kernel options to improve performance?
by cyent from LinuxQuestions.org on (#5P6N8)
So there exists an improved version of the afl fuzzer....
https://github.com/AFLplusplus/AFLplusplus
...somewhere in that readme page is...
> Improve kernel performance: modify /etc/default/grub, set
GRUB_CMDLINE_LINUX_DEFAULT="ibpb=off ibrs=off kpti=off l1tf=off mds=off mitigations=off no_stf_barrier noibpb noibrs nopcid nopti nospec_store_bypass_disable nospectre_v1 nospectre_v2 pcid=off pti=off spec_store_bypass_disable=off spectre_v2=off stf_barrier=off";
then update-grub and reboot (warning: makes the system more insecure)
Anyone aware of any benchmarks on the effects of these on doing something like a large compilation and link?
