There is some variation on these figures so they're to be taken with a grain of salt: with reqres & keepalive filters =============================== duration: 6242 ms without reqres filter ===================== duration: 6057 ms => duration decreases by 3% without keepalive filter ======================== duration: 5802 ms => duration decreases by 7% without reqres & keepalive filters ================================== duration: 5507 ms => duration decreases by 11% View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4147199#...
