Fyi:
Compiled "mkvtoolnix" ( https://mkvtoolnix.download/ https://mkvtoolnix.download/ ) on Gentoo Linux twice, once without and then with the kernel options "pti=off spectre_v2=off l1tf=off nospec_store_bypass_disable no_stf_barrier":
No kernel options:
merge time: 13 minutes and 38 seconds.
merge time: 13 minutes and 44 seconds.
With kernel options "pti=off spectre_v2=off l1tf=off nospec_store_bypass_disable no_stf_barrier":
merge time: 13 minutes and 5 seconds.
merge time: 13 minutes and 28 seconds.
Kernel 4.14.101-gentoo, CPU Intel(R) Core(TM) i5-6200U CPU @ 2.30GHz, microcode version 0xc6, Lenovo X1 Carbon 4th gen, CPU governor P-states set to "powersave".
Parallel compilation set to max 3 threads (" MAKEOPTS="-j3" ") but mkvtoolnix compilation seems to use most of the time max 2 threads.
gcc (Gentoo 8.2.0-r6 p1.7) 8.2.0
I guess that the 2nd rounds have higher runtimes than the 1st ones because the CPU got hotter... .
