Do you have a large iptables rule set that might be slowing things down?
iptables scales with O(n^2); still 250 IPs doesn't seem a lot of IPs.

No this is the output of iptables -L

lvs01 ~ # iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

All i really use is ip masquerading so that my realservers can access
the net to recieve updates everything else is left open.

Just had an idea...

David M has an LVS with 30 VIPs.

http://marc.theaimsgroup.com/?l=linux-virtual-server&m=116613085127672&w=2

His realservers are nat'ed out to the internet. He has to make sure that the calls come out through the correct VIP.
Does this sound like your problem?

Joe
