[jboss-dev-forums] [EJB 3.0 Development] - Re: ThreadLocalPool - Is it working the way we think?

Two issues: 1. the original ThreadlocalPool was designed incur zero thread contention. This changed when statistics were implemented. Right now that uses sync blocks, but it could be changed to atomics. Still it would incur a penalty. 2. a ThreadlocalPool servicing a ThreadPool with a size > 100 will always have a lower throughput than a StrictMaxPool with maximum size 100. The maximum size of ThreadlocalPool is not applicable. To really identify performance bottlenecks within enterprise beans you would need to know: - average queue size - average execution time - average wait time We also need to microbench all the pool implementations to see their effect on throughput & average response time.
