Bela Ban commented on JGRP-2024:
--------------------------------
Sample configs {{udp-largecluster.xml}} and {{fast.xml}} are starting points, but this
largely depends on what you want to do. Is it more Infinispan style traffic? Then UPerf is
a good test, otherwise MPerf might be useful.
I'd start the tuning process at the transport level and size the 2 thread pools
accordingly. For example, if you disable the queue in the regular pool and up the max
size, you'll get more concurrency. But again, it depends on
* How many senders do you have?
* Cluster size
* Regular or OOB messages?
* Blocking or non-blocking RPCs
Further things to look at:
* Can you compress data? -> {{COMPRESS}}
* Flow control; possibly increase credits
* UDP or TCP as transport?
* Message batching (JGroups 4.0)
* Type of message bundler in the transport
* Run perf test and use probe to measure stats and adapt config
* etc etc etc
These are things we discuss in the workshop [1].
