Hi,Maciej,really? it's so exciting. we're choosing framework now,and I prefer wicket, but the heavy session is my care. but there're some questions: (1)where you result from? Is the 20,200 reality request and not from jmeter(or other stress test tool)? (2)300MB/20,000=15KB,Does it mean only 15KB per session? I think 15KB isn't enough for only one page. (3)Would you like give us some experience for so high load web application?
