[eclipselink-users] Speed problems with 1.1.3

[KARASZI Istvan <ikaraszi@xxxxxxxxxxxxxx>]

dear list!

we are developing a web application which is deployed to a GlassFish  
AS and communicating with a PostgreSQL database through EclipseLink.  
two days ago we were in a hurry of a release, on the night of the  
release we have found out that the production server is really slow  
comparing to the test server with the same code on the same HW with  
the same OS (kernel + libraries).

the last two days I was to find out the cause of the problem. I  
checked the HW, ran a lot of benchmarks and profiling, compared the  
versions of the libraries, checked the kernels, etc. in the morning  
I've found out that the problem was with the EclipseLink. on the test  
server the version was 1.1.2 which was running smoothly and fast. and  
on the production server was version 1.1.3 which was running slow  
(considerably - about 20x slower).

i haven't thought that the newer version of EclipseLink could cause  
the speed problems. have you ever experienced problems like this with  
this version? or could you give me ideas why it is so slow with the  
new version?

if you need any more information about the environment, let me know!

thanks,
