oupps, but 50 ms it's ok when you do time to time, but when you have 50 client (and that not too much for a web service) doing this at the same time then the 50 ms become 0.5 secondes .... enalf to make down the services when we know than more than 300000 request (even more?) must be done every days. this is worse when we know that the 50 ms "seem" lost for a simple misc conception (i say "seem" because don't know yet what the prepare do)
