I do not know why you would want to do this other then for testing but --
change your startup script for tomcat to include the option java -classic
.... and you will be using green threads. Be aware that it is now easier
to create a deadlock situation. I believe that it would be a big mistake to
deploy a system with green threads. My system incorrectly reports that I am
using 217 meg of ram but that is incorrect, It is actually using 74 meg of
ram.(with tomcat running) Use gps for a more accurate reading. Pushing the
server hard during testing does not increase the ram used significantly.
(cpu usage reflects as you would expect)
All those processes that you are seeing are simply sleeping threads. They
are NOT using any resources and are being incorrectly reported as consuming
processes. This is the very compelling reason that you would want to use
java in the first place. Native multi-threading. You have a thread pool
ready to respond without the overhead of creating new processes on demand.
Good luck,
Craig
Let us know what you find out.
