If you are using a recent release or snapshot of Tapestry 5.2, you'll find the page pool is gone. Tapestry now instruments your pages and components so that they can be shared across any number of threads (mutable fields now result in writing to or reading from a per-thread HashMap). You will now have just a single instance of each page, per locale. I suspect you'll see a big improvement in throughput and a big decrease in memory utilization.
Can you tell us anything about your app? What are you building that gets that many concurrent users on a single box?
