Bela Ban commented on JGRP-1037:
--------------------------------
OK, so for the regular pool, we could use the following strategy to set the max thread
pool size:
* We know the cluster size
* If we received a message from *every member at the same time*, then we'd need N
threads to process those messages
* Any additional messages received from member P would get added to the table for P and
then the thread would return immediately, so this is quick
* To be able to take incoming messages and place them into that table *when all threads
are busy*, we should add a buffer of 1-2 threads
* So the formula for the max thread pool size of the regular pool could be CLUSTER-SIZE +
2 (to be investigated)
Ergonomics: size thread pools dynamically
-----------------------------------------
Key: JGRP-1037
URL:
https://issues.jboss.org/browse/JGRP-1037
Project: JGroups
Issue Type: Feature Request
Reporter: Bela Ban
Assignee: Bela Ban
Fix For: 3.4
Ergonomics are a step towards less configuration and more dynamic setting of values.
Example: a thread pool's min and max sizes can be dynamically changed, based on
observations. When we have a min size of 10, but the thread pool is always 75, then we
should set the min size to 75 and possibly change the idle time too.
This is just a first step towards ergonomics and needs to be expanded on in 3.x releases
