Given your configuration, it appears that you will have 500 maximum threads. I am a little unfamiliar with the NIO connector, but this is what the documentation says when using useExecutor="true": " If set to true(default) then the max pool size is the maxThreads attribute and the core pool size is the minSpareThreads. This value is ignored if the executor attribute is present and points to a valid shared thread pool. " > 2. doesn't nio work with one thread?

A single thread could never supply suitable performance for a web application. You might be thinking of Comet, which is a completely different beast. http://tomcat.apache.org/tomcat-6.0-doc/aio.html > 3. I shouldn't work with Executor while working with nio connector? Using the executor is perfectly find. I think Chuck and I were confused since the executor is typically specified separately (as <Executor>) but the documentation appears to suggest that an executor will be automatically created given your configuration. > 4. can you send me an example of nio good configuration? Your configuration appears to be good, actually. The only problems are: 1. You are nervous about the number of request processors appearing (and you probably shouldn't be, unless you are hardly using your app at all and you are still seeing hundreds of request processor threads being created) 2. Your application hangs, which is, of course, a serious problem. For that last one, you'll need to take thread dumps to find out what your app is waiting on. You might want to scale back the number of request processors (maxThreads setting) so your thread dumps are small enough to read without losing your mind. My guess is that you are hitting your database thread pool limit and the application is simply waiting for db connections to become available. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkkkMOQACgkQ9CaO5/Lv0PBYWACgwsqRM2XG4N1SOMSt722XlY/Q MbkAnjjThQY/WEFv65JtmkdENyltkFCF =yIAC -----END PGP SIGNATURE----- --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
