Hi

I'm sure it isn't normal, so I'm looking for help. I use TreeCache.put(Fqn fqn, Map data) to replicate about 50 objects.
This call takes from 3 to 80 seconds to execute. Cluster (2 nodes :) is build
over fast and reliable local network.

Execution time analysis show that almost all time is spend in
TreeCache.callRemoteMethods(List mbrs, MethodCall method_call, int
mode, boolean exclude_self, long timeout)

Config at bottom.

Any ides?
