We're having a situation where it took about 5 seconds to get auth TOKENs for 100 users (but only 100 ms for a single user). Does this sound right? Has anybody else done benchmark of UAA perf who can share your experience with me?

Thanks,

What request are you doing to get a token?

100ms to 200ms sounds about the right value to get an Oauth token. We did a
benchmark with UAA and found out that out of the box, the auto
reconfiguration sets the default JDBC connection pool value to 4. You will
run out of connection pool if are trying to test with 100 users and your
requests may be waiting for a JDBC connection to become available in the
pool due to which you may be seeing 5+ second response times with 100
users.

My understanding is calling POST on /auth/token 100 times in parallel. I'll find out more about the test scenarios when I'm able to reach them. Thanks!

Siva brings up a good point, you haven't really told us anything about your
environment :)
