@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...
