CPU-Intervall (cpufreq.sh)

Mit dem folgenden Script wird das CPU-Intervall festgelegt.
#Usage "./nameofscript.sh"
grep -E '^model name|^cpu MHz' /proc/cpuinfo
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
for CPUFREQ in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor; do [ -f
$CPUFREQ ] || continue; echo -n performance > $CPUFREQ; done
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
So konfigurieren Sie die Netzwerk- oder Speichereinstellungen:
sysctl -w net.ipv4.tcp_mem="16777216 16777216 16777216"
sysctl -w net.ipv4.tcp_wmem="4096 65536 16777216"
p | dc'
p | dc'
