RE: Performance Issue/Hang with 1.5 svnserve

Download wireshark and install it on a machine with a client (which will
have to be a different machine than the server.) Go under the Capture menu
and choose "Options". Choose your network interface that you are testing
over (if unsure, keep picking until you get the IP you expect). Clear
"capture packets in promiscuous mode". In capture filter, enter "tcp port
3690" without quotes. Try some operation, and when it seems paused, quickly
switch back to Wireshark, choose one of the packets in the list and choose
"Follow TCP stream." Then check where the stream seems to have ended itself.

Which sort of "slowness" are you seeing? In my case it was clear it was
connecting, but was pausing *during* the connection. Is this what you're
seeing?
