Hmm… Usually 1st request takes some longer (as Java classes need init time etc), after that it should work quicker.

1. Make sure the application has enough heap size. A JVM parameter -Xmx512m usually works fine.

2. Try to run v391. It reports now latencies by a loading of external resources, so you’ll be able to locate a slow responding one (if any), or at least to exclude “network delay” as a problem reason.
