It's nothing too interesting, I don't think, to be honest, which is why I didn't elaborate. Basically, our web service layer is occasionally suffering timeouts when communicating with a tomcat instance that has been inactive for a time. We suspected that this was to do with either - tomcat unloading useful info from its cache - tomcat memory being written out to disk, and then being read back in again The tomcat list hasn't been at all helpful, so I hope that this means that it's the latter, and not really a tomcat problem at all. I'm still trying to get an environment set up where I can actually test what's going on with the paging. >> It was alleged on some site or other (i.e. I googled >> for 5 minutes, and that was what I found - not a scientific approach) >> that Tomcat and Resin are the fastest of the containers (which is a >> significant criteria). > > Similar research that I've conducted hasn't been quite so favourable for > Tomcat. Quite so. A further 10 minutes of googling indicated that Jetty was the best, Tomcat was the best and Resin was the best, and that they were all also the worst. Conclusive ;) The overall sense I got was that Jetty might be marginally better. > Then again, it may also depend on what criteria you are using - > vanilla Tomcat doesn't tend to scale to well with multiple connections. > In such cases, you want to look at something that either has NIO (Jetty, > Grizzly - the refitted Tomcat that is part of Glassfish), or use the APR > with Tomcat (but then if you are having issues with Tomcat, I can't see > that they are going to be helped much by including native code!) That makes the possibility of using Jetty seem quite attractive, though. If this problem persists (we have done some network tweaking which might have had a knock on effect), I will try that route next. Thanks for your feedback on this, Graham.
