Hi Jesse, I thought the ContextLoaderListener would just be called once on startup. Does it do something on every request?

I remember that long time ago I did a comparision for the same reason... and we found out, that the xml-processing on the solaris box was WAY slower than on the Win-Box.

I checked for missing tld/xsd warnings and we aren't getting any even though, as you guessed, the Solaris server does not have internet access. However, I have managed to find another of our jsf applications which did not have the 4/8 second page response delay and so I slowly migrated this to be more like the troublesome application. The main problem occurs when I include <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> in web.xml. Yes, the problem also occurs if I use ContextLoaderServlet too. After including ContextLoaderListener performance deteriorates considerably from 2 second response to more than 4 even if I don't load any spring contexts. Has anybody any idea why ContextLoaderListener slows down my application running on Weblogic 8.1 on Solaris? Many thanks.
