I don't believe synchronization can have a big impact. The question is, what change in latency did you expect. You are doing 100 times more work. But what kind of work? Are the threads mostly waiting on the server or are they mostly processing the response stream? So is the workload CPU, memory, or signal (wait) intensive? Maybe your processing is just wasting memory and all your VM is doing is GC? --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
