Congestion control was + overshooting the congestion window during slow start, particularly for + onion service activity. With this fix, we now update the congestion + window more often during slow start, as well as dampen the exponential + growth when the congestion window grows above a capping parameter. + This should reduce the memory increases guard relays were seeing, as + well as allow us to set lower queue limits to defend against + ongoing DoS attacks. Fixes bug 40642; bugfix on 0.4.7.5-alpha. |
