I have tested squid-3.0.stable13 for round-robin loadbalancing. I found it behaves as not the same as the before version of 3.0 branch. For example, there are two backend servers, server A and server B. >From squid to server A the connection is fast, but to server B the connection is slow. So under this version of Squid it will deliver more requests to server A than server B, even it's using round-robin. But in before version of Squid it seems most likely to deliver the traffic averagely. Is it the right fact? Thanks. Jeff.
