There shouldn't be any synchronization issues, here, unless your applications have introduced them. Each request processing thread operates independently and only encounters synchronization when entering/exiting the connection pool or accessing session data. If you make a loopback call (one request triggers a request back to the same Tomcat instance), the two threads shouldn't interfere with each other at all (again, unless your webapp does some locking). > Does any one have a reason for such an increase in time, from 1 sec to 16 ? I can't imagine why this might be happening. Is this easily reproduced? With a 16-second delay? If so, issue a request to the primary service, wait 'till it stalls (which should be pretty much immediately) and then take a thread dump of your JVM. In fact, take several and save them to separate files. Then, look to see what (if any) differences there are and what your threads are doing during that delay. This will give you some insight into why your threads are waiting. Another option for you, instead of setting up two <Service> declarations, would be to set up a <Connector> that binds to 127.0.0.1 and is used exclusively by one app to access the others. That way, you could ensure that there are enough threads to service as many requests as come into the primary webapp even if all of them require a call to the secondary one. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkr7M8kACgkQ9CaO5/Lv0PAF8gCgqGnzgxJcKwD5x6HC8nzUXno/ iUMAn0kQK4ZJOjPrOQG0stohhHEc779O =0qll -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
