@Don - yes @Toby - yes on the dev appserver the first request also takes about 6 seconds. Watching the info log I see it finishes initialization of my servlet after 1.5 seconds and then starts up the datanucleus initialization, which takes about 4-5 seconds. Attaching a profiler is a good idea and I will do it tonight but I'm 99% sure the hotspots will be in org.datanucleus packages, which is why I was posting here to hopefully find the ear of Max Ross or the like...
