[Performance] Searching for jsf-performance-experiences with 200+ users

[Clemens Schneider]

Hi there,
does somebody has gathered some founded experience in a jsf-production
environment with 200+ users, accessing the website quite frequently in an
intranet setup?
I could only find some discussions dated early 2004 that stated, that the
performance isn't that good. Can you point me to ressources where I might
find some stress-tests or performance discussion on a current myFaces or JSF
1.2 RI release?
Thanks in advance!
greets,
clemens
