When you catch threads doing socket I/O, they are almost always waiting for input from the client. If you're using keep-alives (highly likely), that's the normal state of a thread. This likely means you don't have enough requests coming in to keep the threads you already have busy; adding more threads won't change that. Using the NIO connector will avoid having the threads sitting around waiting for socket input, but it won't make your CPU busier if you have nothing to do. Why do you think having a lot of threads is a Bad Thing? Are you running out of process memory space? - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
