Re: [tor-relays] CPU saturation attack/abuse

[torix@xxxxxxxxxxxxxx]

Dear Dhalgren Tor,

I have been running a middle node with the ingress connexions being 5-10% fewer than egress connexions since it started about 11 months ago.  changing Tor versions twice has not made any difference in this, the current version being 0.3.2.10 that came out yesterday.  But I'm only running only about 2,000 on each side (19xx ingress, 21xx egress).  I assumed that was normal...
