JBossCache Ticket Registry performance under load?

[Brian Donnelly]

Thanks Scott,

I've attached my jbossCache.xml config file.  It is almost identical to the jbossTestCache.xml configuration included in CAS 3.0.6.  I did have to comment out the authentication protocol version tag because it was generating errors.

If anyone has any pointers or would be willing to send their JBossCache configuation parameters, I'd be very appreciative.

Thanks,

Brian Donnelly

Brian,

We don't deploy that at Rutgers so I can't comment on that.  A few people
have deployed it in production without issues.  Maybe you can include your
configuration file and those who have deployed it successfully can compare
it to theirs if they get a minute (hopefully).

Thanks
