Remember that you want to make sure that your test is valid by generating load from multiple servers and not just one host which might limit itself. Our testing[1] indicates that you can fill the network before Tomcat begins to struggle with moving bytes around. Your application is far more likely to be a bottleneck than anything Tomcat related. > 4. Any references / biogs that I can refer regarding this topic 5. > Any suggestions from your end. It sounds like you have a single server running your application. I would recommend more than one for fault-tolerance and high-availability. Users are happier with a slower, available service than a fast one that isn't reachable. :) > Note: A brief about the the web application.

That doesn't give us much information. What really matters is the amount of information going over the network. Tomcat mostly just pushes bytes over the network for you and dispatches everything to your application. So unless you are having a specific problem, there really is nothing to do with Tomcat to make it "faster". It's already pretty much as fast as it can be. - -chris -----BEGIN PGP SIGNATURE----- Comment: Using GnuPG with Thunderbird - https://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAl0BApoACgkQHPApP6U8 pFgq3xAApCqyUS3DUVwF2PNwhNStms7Y8gbW9A53PInqeu9c7vyM6JN2e8DexccG N9ZTZXv8EEYFXSJJasad3S7d57pVON/TgCK/+XNcFLMSajn/6vhNJF6j6WoqRLmo rbkSFylG6rKytn1vd8fgw7/o3yeahUbyDHVwn3hY3ZTHXYVO9tM2zgnHe65FB7pO M/N9a52NXeObvt9KrssMVHjH7cDBTh6gOAOKq7nVD8qi7S6nU4SLBJn7bhqNRwJc vTQfJgq1jEKe2c3O2ynbWckzXzRCqq/rmFWAU8srsdVbBxikzz/W2kIjsWxwQf5s sIbzh3ZB03XE0ko+Dnr16DmZMK7uWW+J2IAoQr+XOJnIkz6t7DuV3q/8q0+Q9gnf fXya+xK5PJsOoKxxPyqOVw/C6ZdGoPwJDDVlpJR8RrfdozL+zycRC8uIXoHOvr7H PoDDwnfzR410d5mXt0vBSXbndJZl/Bjv68bfUfHi5RvJr4GYJtgVqHl71cLD6aSy WGacv4rBe+B5LWexDso/Ajb3aE/DB7at+EpB4ZThKlla4Et0K5EVOZ71YAuSfbIO /IvSXpZcwa5b1YIZ0Fdrnv5QpBdY0SyuRB8ImhUcqQi46VoYdyao1UbjN72aYPX5 YpaDnK+EDMLrxOBwdURJUMEUWJUWjrlSvVsZ4DmxqDUBWN4HFDU= =q2wh -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
