Hi David, not speaking especially on Enhydra 5, more generally on Java on Linux... Quoting a post on some other mailinglist "I think what you're looking for is the difference between green threads and native threads. If you search for this it java.sun.com you should be able to find all about it. In short it boils down to mapping Java threads to native OS threads or emulating threads inside the Java VM (=green threads). Both have their advantages and disadvantages. For example, if I recall correctly, green threads perform better because there is no need for context switching at kernel level; however, you need to treat green threads as cooperative instead of pre-emptive multi-threading, so you need to use Thread.yield() or sleep() or do I/O, for example" 30 threads is fine. I'm running Tomcat with ~20 Applications deployed makeing a total of ~200 threads.
