Changed subject: it's APR (Apache Portable Runtime), not ARP (which is something different).

The better question is how many simultaneous /requests/ you expect. 2500 users might not require 2500- simultaneous connections. > 2.

Yes, you can use an executor. If you don't specify one, a <Connector> will create a default <Executor> for itself. If you expect to have multiple connectors and you want them all to share a pool of worker threads, then you'll want to configure a single <Executor> and then reference that from each of your <Connector>s. Are you going to be using SSL? If not, you might have slightly better luck with the NIO connector (APR/OpenSSL has a performance advantage over JSSE), plus you won't have to build and babysit tcnative, etc. Problems that occur at the NIO level will likely throw exceptions while APR can bring-down the whole JVM. It's rare, but when it happens, it's catastrophic. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJSOxwzAAoJEBzwKT+lPKRY2M8QAMqvN5KpOzmhBJbSlzQ770tr xP8WiIrtloormFI9+XpT6ZJ2c1v5fx/MjlhSjhXKQd6M54pC9MKIXmM4zrpaOtPh 6amiRh7dNJXnYsUXKylw5O8lI4frsxbCnBS5wtXL1zywXL7uXbj37w4GbEzaYkql 5hL7z65/pBIhk9QTCfeUE7gvk1MQNMhkfDgGEHanWmwH3rCBucNjF7O8aUn8OlZy 3guTpvfo2TpPiSA6tpEgTliqR7ZTg19KN8flXtiN1+M/L+OGips1ihOPRYxj4Osc A51pltqdEyv1cSR3oVyb4xYXCYHjO0kxoDNIpDr+HZp4Xw7bdb+VvXZamyffvOyP dgs8zRRGsmKpVaPXnKcjdhNlbtCGKppQFuMeYxz975/dVxpHXcr3xmPKg33H31Jd OnrYvyTjxeP6Y/cj1AYUZYwr+yzg3FBPv8S/O2POy1eZDTPVwr0uKfIlNYl6bzrr PiEizoq/UYuIK+wst9NZsztAIf70VWmCbN1lW5oz090tXR0yU2xxdFhh3P7yUV/j LxvQqGshX5uHW1sySGeznluof9t/RPd1938Sx0ML94EHmi+U7Mb+Y7u+jxy4skxT m58Q3vxTYZrv78ayEfXP7KTdDXGItNwVwbILMpLopQ6oJe0N7ay8bbO5tj29/aR4 oOuFKKtVOXjWpZ+nC1Om =AjzT -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
