[tor-relays] [WARN] Your computer is too slow to handle this many circuit creation requests

Hi,

I see a number of warning log messages on a dedicated server: [WARN] Your computer is too slow to handle this many circuit creation requests! Please consider using the MaxAdvertisedBandwidth config option or choosing a more restricted exit policy. [27615 similar message(s) suppressed in last 60 seconds]

The relay is running on a dedicated hardware with the following specifications:

CPU: Intel(R) Xeon(TM) CPU 3.00GHz RAM: 6G Kernel: Linux 3.16.0-5-amd64 Tor version: 0.3.2.9 flags: Fast, Guard, HSDir, Running, Stable, V2Dir, Valid exit policy: reject *:*

Setting the NumCPUs option to the actual number of CPUs (2) didn't help. Is this hardware really too old/slow to run a relay on one ethernet Gigabit link?

Cheers, ~Vasilis
