need this and it slows things down for servers. For clients it's not much of an issue, since traffic rates are low. However, for server-to-server links it is an entirely different matter. It is (only) noticeable if you have lots of traffic, such as when there is a lot to sync while linking two servers, and especially when the two servers are geographically further apart. Tested with 100,000 G-lines on both sides being synced (20MB traffic): * 20ms RTT (same country/state): speed up of x3 * 200ms RTT (transpacific): speed up of x6
