Are you configuring a single server, or a farm of server? Is a farm, how many nodes? Are you using distributed sessions? You have really provided no good information with your request. If I were a consultant, I'd tell you that your best bet is to bring-in my Sharepoint and SAP teams, and after a few tens of million dollars and a few years, you'll have everything your heart desires. But I'm not, and those products are rarely the proper solution ;) You didn't even say what Tomcat version you were running. I'd recommend upgrading from 3.2.3 to something more recent. > This concurrency will continue though out the day.

Aah... the perennial question: where is the "fast" configuration switch, and how do I turn it on? The short answer is that Tomcat is tuned pretty well in its default configuration. Only you can determine what settings are appropriate for your needs. Nobody can give you any tips of tricks to speed things up. That being said, Tomcat currently ships with the default BIO (blocking I/O) connector enabled. Using either the NIO (all Java) or APR (native) connector would probably be an improvement. If you are using SSL, I highly recommend the APR connector, as there is a measurable performance improvement using OpenSSL over JSSE. If you need to be able to handle 1000-1500 simultaneous connections, then you are going to have to either use more servers or raise the limits on your <Connector> (which default to 200 threads). The attributes you want to adjust depend upon the Connector you are using. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJSMK8ZAAoJEBzwKT+lPKRYIWgQAI9mCcSsc2OHrf3g3bPe5zzN GdRcBlVcY5LC6ZATOe0ychJj5268hV2N2GZmS2oasUHg8UNI0YKPG5+peQXaVBgP Cf/HQhCAXTxMzjfkCRQE/PHsaqOS3T10mbbwBfWgZiZ9yhlNlJ/5siswUKwdVlcM c8aRafWCYvwWIjeiwpWxX04GFvs6m2c2NlgdO56uVqsIPndup8QDmUOKF1D65II1 Yi4AjNkf/DjG50fbDE1K13qf/6c2x8kDJMEQcYWL7aEHwDz7Lhl+59A9UqI/ZFVr Lb+ASyb5qjTgrOgi887iIn4wnq8fl92sZg1Uz/rasqF/OBy1bwBedmeVEioEhDU0 8Tm9elxRwbY7Eh0Oil6YvyhOaB6TEcKwt5kCoLEJVcDnksdczaaOO5MG/X88k/+7 S0tQWkKSlvDFfL1GZxrcHMvNU/85NmCrpQp2zjBt7ysFBjT4rGuwmj3r6Q0hMth7 vUqmJ5XcO0E9Ahd/XiW3vYMivIlwpGru301NCxKkeWSUX+aAOuNNTOCt1wriXXCw 2YejCPM/s5oTWs5UxEGgOHEdWR6sg3AWmtsK4bfa8hbDiKgCpXlCRzuwxzbN/WyR F8EBSs+DxP1+cBAxNq1DPnCgxnGzx5n2NR6rjj6lxZL+9sl5S/8Bb430jyvbZNWa pFy6NACqKLwvoq545N4Q =X2MW -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
