Subject Geronimo 2.1.1 running a report 2-3 times slower than Geronimo 1.1.1
Date Fri, 05 Dec 2008 01:04:44 GMT
This has recently cropped up at my workplace - We have a report that
runs every night and dumps a reasonable chunk of the database to a
text file. The report itself is quite inefficient (it stores
everything in memory until it's written to the text file, for
example), but a simple switch from Geronimo 2.1.1 to Geronimo 1.1.1
results in the file taking 2 - 3 hours instead of 6 - 8 (or more!)
hours. I'll be looking into this myself, trying to pinpoint if it's
our fault or Geronimo's fault, but I was wondering if anyone had any
ideas, or if there are any known areas where Geronimo 2.1.1 is slower
than Geronimo 1.1.1? Likely places are in the XML libraries, or in the
Database Pool/Connectivity from what I understand.

Any suggestions on how to investigate this would also be appreciated.
I'll add in profiling code to our application in the relevant places,
but I'm not sure what else I should be doing to get to the bottom of
