Web services not working with firewall

Level 1

                   we have instaled and implemented a FWSM on cisco catalyst 6509E and defined two virtual contexts.

one of contexts work as datacenter firewall. initially it is configured to allow all traffic to datacenter VLAN. (permit any any)

on test, it worked fine, except for one problem: all web services had degradation in performance, all server-client (non web) services worked very fine. additionally all https servies worked well.

this was very confusing, becasue users connect to the web server bypassing the proxy, web services are expected to act just like other ones.

Does any one have an idea?

could be several things:

do you have inspect http enabled, are you close to the # of connections per second or throughput limits?

are packets out-of-order or fragmented and FWSM has to reassemble (show run all fragment to check)?

any logs or more details you can share?
