The update went very smooth with this guide
All my work thus far has been on the database side, mapping incoming xml documents to my model. But there have been some significant performance increases in active record. My unit tests were taking on average 78 seconds on a 3.4 ghz pentium box running FreeBSD 5.3. That time has now been cut to 62 seconds on the same box. And that is with transactional fixtures turned off and instantiated fixtures turned on. Not too shabby!
Great work guys! I can’t praise you enough.
