The usual causes are
o identd/authd
o routing problems within the LVS
o DNS lookups (which can be slow)
tcpdump is the usual tool. You'll need a client which
can reliably get the pause and then watch the director
and the realservers with tcpdump. You should try to figure
out ahead of time what is different about the clients
that are getting the high latency connections (put a machine
with a different OS at that IP, use a different client,
eg telnet instead of http)
