Do you have any idea why the director might limit the performance of our 
system? Without LB I get 100 connections/s to the real IP address of a real 
server. When I address the virtual IP of the director I get a performance drop 
to 1 connection/s.

tcpdump shows that sometimes I have no traffic at all on the line to 0.2 sec.

Any ideas? Thanks.
