JBossCache Ticket Registry performance under load?

[Scott Battaglia]

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
-Scott
