are you sure this server can cope with 50 simultaneous requests? see my previous reply for calculations based on cpu. If not then putting it up that high would cause more problems than queuing the requests. You really should try fusionreactor as I suggested, there is a free trial version if that is what is making you avoid the suggestion. This will show you much more info about memory, cpu usage, how many requests are running, how many are queued, what requests are taking a long time etc.
