IdPProdLoadTest having connection refused exception

[Peter Schober]

Just some minor comments, I haven't used IdPProdLoadTest or grinder.

I haven't had to service c10k yet but I'd suspect you'd need more RAM
and possibly a larger perm gen space for the JVM. But the error
message would be different then, of course.
(Also I somehow doubt you can really test c10k from a single machine
as the client(s). But I may be wrong.)

There should be no need to have Apache httpd running on your IdP
(unless you actually need it for some functionality Java cannot
provide). If you do need it why not use the more modern MPMs like
worker (or event) instead of prefork?
You might be better served with running just Jetty, performance-wise.
