What is your Apache httpd configuration for StartServers/MinSpareServers/MaxSpareServers (for prefork MPM) or startServers/MinSpareThreads/MaxSpareThreads (for worker MPM)? What are you settings on the Tomcat side for your AJP <Connector>? > From the research get to know minSpareThreads and maxSpareThreads, after set > the configure it can handle more to 400 ~ 600 minSpareThreads and maxSpareThreads shouldn't be used when using AJP: you should be using the exact number configured on the httpd side.

If you want a dynamically-sized thread pool, use an <Executor> instead. http://tomcat.apache.org/tomcat-6.0-doc/config/executor.html > (2nd) From read 1 by 1 at the forums about Performance tuning - tomcat, some > mention keep hit > 20k per seconds, how their do it? That depends a lot on what kind of load it was under. Serving static files is fast. Running database transactions is slow. Also, sizing the various pools can have an effect: you can max-out the throughput of a single client but still have plenty of CPU time and I/O time available on the server. If that's the case, make your connection pools bigger. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk3b86gACgkQ9CaO5/Lv0PD/BgCgn4GRuqON8mS9Y0IO9j8ra0Ou TTgAn08U0AgGtpi6JE+nnk1OLNLlhzDK =zahv -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
