Hi there, Please check to see if you have excessive debugging turned on (in server.xml) and check your disk i/o (vmstat or some other tools), check to make sure that you're work directory (and your tomcat directory) are not NFS mounted or in a shared volume somewhere.
Also pheck the hops between the source and target box (traceroute) and see if there are any delays or network connectivity problems during your testing (has happened to me more than once) check whether your machine(s) are communicating half/full duplex or set to auto-negotiate Then do the following... hop on source box and run (without the pound symbols) #telnet localhost 80 (or tomcat port) #GET /path/to/test/servlet HTTP/1.1 #Host: <virtual_host> and time the response. If its really slow (from localhost), check the java settings (-Xms and -Xmx and your gcc settings if you have any) Finally, if your app has a db or some other external i/o (i.e. ldap) remove those from your test and construct a stripped down version of your app and re-time...
