My application used GNAT with lots of long-lived threads. You can read my report at http://www.grebyn.com/t1000 - it was impressive enough that I actually WON the evaluation system from Sun in their Open Performance Contest (see http://www.sun.com/ tryandbuy/prm/perf/winners.jsp for other winners - primarily web servers, databases and other transactional systems). -- Karl --
