RE: After statting the server login time taking 2 minutes
What version of openJPA are you using ? Is the application gaining performance after running for some time ? If yes then enhancing at build time will definitely help. I think as Jean pointed out it is better to enhance at build time regardless. What about thread dumps ? Can you please take 3-4 thread dumps in an interval of 15-20secs, at the time of delay. (kill -3 <> in unix based machines will give threaddump in the stdout. On windows you can use on your command prompt that starts the server) Regards, Ravi. -- View this message in context: http://openjpa.208410.n2.nabble.com/After-statting-the-server-login-time-taking-2-minutes-tp4962106p4968492.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
RE: After statting the server login time taking 2 minutes
I have had a similar issue for a couple of months now, I enhance at build time, also checked that the classes are persistence cable. Still runs like a dog, a couple of minutes to retrieve a few thousand records is par for the course. I a not sure what started it, things were much better up until a couple of months ago and even reverting back to an old source version didn't fix it. Tried different servers and even blew away my DB and started again. I can use standard SQL to retrieve the same data in milliseconds. Turning on TRACE logging to trouble shoot it slows it down significantly more so it's a catch 22.
