[appengine-java] Datanucleus initialization performance

2010-01-05 Thread Todd Lindner
Since Google App Engine will power down the app if there aren't any requests for ~10 minutes, it has to re-initialize your application often. Not a problem I was able to trim my app init down to about 1.5 seconds, so its reasonable, but datanucleus itself takes about 5 seconds on top of that

Have you tried enabling offline precompilation? On Tue, Jan 5, 2010 at 8:52 AM, Todd Lindner wrote: > Since Google App Engine will power down the app if there aren't any > requests for ~10 minutes, it has to re-initialize your application > often. Not a problem I was able to trim my app in

Also, can you duplicate the slowness in the dev_appserver? If so, you can hook up a profiling tool yourself and see if there are any obvious hotspots. On Tue, Jan 5, 2010 at 12:44 PM, Don Schwarz wrote: > Have you tried enabling offline precompilation? > > > On Tue, Jan 5, 2010 at 8:52 AM, Todd
