Subject RE: javagroups questions - Was: Jk2 object model
Date Wed, 14 Jan 2004 18:19:06 GMT
hi Henri,
When I used JavaGroups (not anymore because of licensing) it was to do
session replication.
Any type of replication or clustering will always impact performance in a
negative way, but instead of you achieve fail over and high availability.

Now I use standard TCP connections, they are very fast too. Most of the
performance enhancements I made was in other places.
The neat thing with TCP is that it has built in flow control and NACK. You
can configure JavaGroups to use TCP connections,
but in my case, I needed to have a pool of them.

what are you leaning towards?

Filip

Did someone here (may be Filip), could tell us if the use of
javagroups instead of standard tcp connections could have
some speed impact (negative or positive).

Just to have some clues in the current reflexion of jk/jk2
successor ....
