www.fabiankeil.de/blog-surrogat/2022/06/22/clock_gettime-patch-fuer-tor-auf-electrobsd-getestet.html
Andreas Kempe veröffentlichte gestern einen Patch auf der Tor-Relays-Mailingliste der unter FreeBSD die Tor-Performance verbessern sollte und rief zum Testen auf.
Ich habe den Patch in die ElectroBSD-Ports aufgenommen und auf einem physikalischen Server getestet auf dem das von Andreas mitgelieferte Benchmark-Program einen Performance-Unterschied von weniger als Faktor vier ergab:
[fk@elektrobier /tmp]$ ./bench CLOCK_MONOTONIC: 0.041536 s CLOCK_MONOTONIC_FAST: 0.013998 s
Eine signifikante Performance-Steigerung oder Load-Reduktion konnte ich nicht feststellen:
