Jason,
we have been using orion in two production environments for about 2 months
now. the load we put on it is not very much in terms of concurrent requests
but we have lots of applications making heavy use of CMP entity beans (e.g.
an online store and a content management system and several smaller
applications). we are very satisfied with the overall performance but do
experience occasional crashes (the jvm eats up 100% cpu and has to be
restarted). the problem is that I'm not sure if this is orion's fault or
maybe a jvm bug (we're using sun jdk1.2.2 production release on linux) or
even a problem with our code that can be remedied by setting a conservative
transaction timeout. it's so hard to diagnose because we cannot reproduce
it. I would suggest you set up your deployment and pound it with some load
testing scripts or tools and see if it remains stable, which it probably
will. we're still rather happy with orion in spite of those problems. there
are things that are suboptimal for production work like the startup
performance and memory consumption when you have deployed a large number of
applications or the lack of management and monitoring features but then
again we look at the price and realize it's still a VERY good deal.
Hope this helps a little in making your decision. I know exactly how you
feel ;-).
