Java Application, WorkManager and a high workload
I'm working on an application which interacts with hundreds of devices across a network. The type of work being committed requires a lot of the concurrent threads (mostly because each of them requires network interaction and does so separately, but for other reasons as well). At the moment, we're in the area of requiring about 20-30 threads per device being interacted with.

A simple calculation puts this at thousands of threads, even up to 10,000 threads. If we put aside the CPU penalty for thread-switching, etc., how many threads can Java 5 running on CentOS 64-bit handle? Is this just a matter of RAM or is there anything else we should consider?

Thanks!
