Srcds performance is not bounded by syscalls. There aren't very many
syscalls in srcds' hotpath (except for maybe networking), and since KPTI
is only activated during a sysenter and sysexit, I wouldn't expect
/Meltdown/ mitigations, particularly KPTI, to have a noticeable impact
on srcds performance.

Hi,
what are you seeing as performance impacts after updating the kernel
and microcode to patch against those two hardware vulnerabilities?
On our test before/after we are not seeing negligible difference (if
none at all), is this common to everybody and therefore csgo code
didn't benefit much from the speculative predictions?
Cheers,
Marco
