hi Christophe,
Comet seems like it's addressing the issues I have ... it looks like it is
implemented with a fixed-size pool of active threads, each dispatching
events to what could be an unbounded number of listeners ... I'm going to
try a scale test with Comet and report back ...
Stepping back
Brien,
Depending on the HTTP connector you use (may be basic HTTP, APR or NIO) and
whether you use the comet API or not, the limit to number of maximum concurrent
long-lived connections in tomcat may be very different.
In my experience, the most scalable is with:
1) NIO + comet or APR + comet
2)
