Here is the minimum amount of information I need in order to be of any
help at all (not out of will but out of ability).  

1. The simplest, smallest amount of code which reproduces the problem
(rip out the JDBC and stick in dummy data, and try it).

2. The simplest input spreadsheets (if any) that reproduce the problem.

3. The simplest output spreadsheets (if any) that reproduce the problem.

Without these I can only:  
1. Relay personal experience
2. Point you to the unit tests which do similar things and run in far
less time. (we have like 300 unit tests, some of which do really really
big things, and all of them have completed (on a 900 mhz athlon) in
under 4 minutes.  Or the results all happen in under 146.604 seconds on
an HP LC2000 (733mhz PIII) (those are the results here:
http://jakarta.apache.org/poi/tests/junit/ of particular interest is
this test:
http://cvs.apache.org/viewcvs.cgi/*checkout*/jakarta-poi/src/testcases/org/apache/poi/hssf/usermodel/TestWorkbook.java?rev=HEAD&content-type=text/plain
see "testManyRows" -- it completes in about 15 seconds on the PIII)

When SOA Workbook comes out or POI 3.0 starts development we'll be
reducing POI's memory consumption by 75% and performance will increase
by a factor of about 2.
