Thanks Christopher, I have not started using 7.0.30 yet and I do have connection pools setup on startup I believe 5 or 6 of them which may account for the 20 seconds.
What I was interested in is after startup using 7.0.30 has anyone noticed a performance improvement for their apps?

As for startup, I just restarted my local dev instance (running 1 webapp with a reasonable amount of db-loading in a ServletContextListener): Sep 18, 2012 3:04:29 PM org.apache.catalina.core.AprLifecycleListener init INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /usr/local/apache-tomcat-7.0.30/lib ....

My system config: Mac OS X 10.8.1 Oracle JDK 1.7.0_07 Tomcat 7.0.30 Intel Core i7 2.5GHz 2x4 (8 logical cores) 8GiB RAM There are 3 things I can think of that could make your Tomcat start slowly: 1. Insufficient entropy in /dev/random 2. DNS timeouts 3. Your webapp does a lot of stuff on startup - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://www.enigmail.net/ iEYEARECAAYFAlBYyyUACgkQ9CaO5/Lv0PAb8ACffNZc584OIXwKQZkaUXOT6MAj bewAnRBCcBqgm/L0n86PouPUC4WeFc41 =HGEj -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
