Oneprovider Dedicated Server - Capped CPU?

webeast

Hello,

I just got dedicated server from Oneprovider. It has Xeon E3 1220 3.10 GHZ cpu but I noticed it is capped at 1600mhz.

I didn't see any information about this on their website..

Should I contact them?

It's most likely not capped, but the CPU most likely is running on a dynamic scheduler that scales up or down the cpu MHz depending on the demand/load on the CPU

You can grep the "cpu MHz" and see the CPU Freq change every few seconds or simply run a benchmark like geekbench and see if the CPU Mhz goes up.

if it stays stuck at 1600~ Mhz even during the benchmark, have a look at sensors via the lm_sensors package to see the CPU temps, if the CPU is overheating or similar (though you'd also see warnings under dmesg), as that too can cause the CPU frequency to not scale up.

I think you're right. Thank you

Maybe its on power saving mode. Check and try changing to Performance mode.

Launch two shells
Run a CPU-intensive task in one shell (e.g. install 7-zip, run 7zz b)
Watch the CPU speed in another shell (e.g. watch -n1 "grep Hz /proc/cpuinfo")
Delete your thread on LET (just kidding)

This is how you set it on performance mode (on archlinux):

cpupower frequency-set -r -g performance
