[tor-relays] tor cpu / MBit/s benchmarks

[tor7]

> You can test how much Tor traffic your machine can handle with chutney:

I'm asking to find out which CPU to buy (I don't have the hardware yet to test
and would like to find out before buying), that is why I was asking others for their
eperience.

I was curious, is this expected output?

chutney/tools/test-network.sh --data-bytes 104857600
test-network.sh: using CHUTNEY_DNS_CONF '/dev/null'
test-network.sh: no $TOR_DIR, chutney will use $PATH for tor binaries
test-network.sh: $CHUTNEY_PATH not valid, using this script's location
