Thiago, Thanks for the quick reply. I haven't configured the tapestry.page-pool.* symbols so am using the defaults for them. I'm not at the stage yet where I am profiling with some load testing software - this is just something I noticed when visually monitoring the relevant java process. It is probably an unanswerable question - to find out whether the increase per request is down to sloppy coding within the application, or an expected allocation by Tapestry that will be reclaimed / managed as necessary.
It is good to hear that previous posters have found that after significant load the memory usage has returned to an expected level. I'll have a look through the archive and see what tools they were using and try to get some of my own figures for a realistic load test.

Have you tested making 1k or 10k request and then taking another used memory reading? Some time ago, someone here (sorry, I forgot the name) posted a test like the one I'm suggesting above (a load test). It found out that Tapestry, after a large load, had its performance back to normal (i.e. before the large load).
