RE: Perf Issue: HttpClient.executeMethod takes more time if there are more number of threads in the process

Complete stab in the dark here ... Tomcat serves a maximum number of threads at a time (request processing threads). It may be that Tomcat's timings are accurate for the threads *when* it executes them, but your HTTP Client will be seeing a queue when Tomcat has no spare request thread

RE: Perf Issue: HttpClient.executeMethod takes more time if there are more number of threads in the process

Hi, Tomcat's max threads by default is usually around 75. I you fire 10 at it then they all get serviced immediately. If you send 1000, all 75 get taken up, meaning a queue forms for the 1000-75 remaining threads until Tomcat has spare threads for them. Allistair -Original
