Subject Re: Tomcat maxThreads
Date Mon, 24 Sep 2007 20:37:12 GMT
Hi Filip,

The reason I want to use more threads is because of the nature of our AJAX
client.  'Sleeping' threads on the server seems like a viable option
compared to polling, and therefore I'm wondering how many threads to use.
Other options include Jetty 6 'Continuation' or equivalents -
http://blogs.webtide.com/gregw/2006/07/25/1153845234453.html to handle this
problem.  I'd prefer to stick with Tomcat if it is scalable with AJAX
clients that require a lot of talk between client-server.

Regards,

Mike
