[tor-relays] Re: CPU requirement gone up?

[DocGerry via tor-relays <tor-relays@xxxxxxxxxxxxxxxxxxxx>]

Thanks prompt reply

Its only TOR using my CPU

I just noticed this is from the very start up when building circuits and no
users. 

Also I am using 3 different providers in 3 continents, and the results are
the same, so I doubt local VPS sharing it the issue on all three at the same
time.

A VPS is shared and the timeslots for your CPU cycles are too. If the system
is heavily overbooked (common there to achieve the low price), the CPU
cycles available to your system are that low that processes need to wait.
Have a look at load avg in top/htop.
If that is more than 1, processes needed that to wait. If this is much
higher, the system is overloaded.

Also check which processes consume much CPU time.
