[jboss-user] [JBoss Cache Users] - JBC spends 90% of its time in TPE$Worker.run

[chtimi2]

I'm benchmarking JBC writes with our application POJOs (80% update, 10% create, 10% delete).
So far it is too slow for our requirements, but i haven't spent a lot of time tuning it yet.

The topology of the bench is: 
-there are two nodes, on a local network
-i write to a node A (always the same), and writes are replicated to the other node B.

I profiled A with Visula VM, and 90% of the time is spent in java.util.concurrent.ThreadPoolExecutor$Worker.run.
VVM also says that this is called by threads like "OOB-something", and that all the time is spent in the "self-time" of the Worker.run method.

What do these symptoms mean and how can i speed up my writes?
