hi, i use threads in order to send http requests.That is that each thread sends a number of requests, gets the responses and measures some things bytes,pages etc Each thread also counts the round trip time: lala1= new Date(); //Sth like: response=connect.Get("www.contra.gr") //***A*** lala2 = new Date(); rrt=lala2.getTime()-lala1.getTime(); The problem is that when i use many threads that send many requests the rrt i get is just not right,because some times a thread stops in the **A** point in order for some other thread to continue and so on...... Any idea pls thanx    More>>
