I have a web server who's perfmon stats report a TCP retransmittal rate of about 10%.
I also have a client who makes heavy use of this server reporting poor performance.
The performance problems started when we moved the server to a new hosting facility.
Does the high retransmittal rate strongly indicate a congestion issue somewhere between the server and the client?
I've done trace routes between the server and the client's public IP and the RTT times are consistently good. Does this evidence weaken the case for congestion?
