I’ve been experiencing overload on both my relays, which is not the usual. Running 2 relays on 4 cores and 8GB of RAM. RAM is not an issue but CPU load is usually at 60%. These last days it’s been over 80-85%, getting warnings from time to time about my computer not being able to hold that many circuits for long.
Over a span of 20 days uptime:
06:08:12 [NOTICE] Heartbeat: DoS mitigation since startup: 1.078 circuits killed with too many cells, 60.081.539 circuits rejected, 751 marked addresses, 6 marked addresses for max queue, 88 same address concurrent connections rejected, 0 connections rejected, 1.633 single hop clients refused, 479 INTRODUCE2 rejected.
06:08:16 [NOTICE] Heartbeat: DoS mitigation since startup: 1.151 circuits killed with too many cells, 40.438.538 circuits rejected, 727 marked addresses, 1 marked addresses for max queue, 883 same address concurrent connections rejected, 0 connections rejected, 1.244 single hop clients refused, 0 INTRODUCE2 rejected.
I’ve considered about further configuring my relays in order to handle a higher capacity, but I’m not sure it’s the right thing with just 4 cores.
