Thank you all for your thoughts/experiences. I concluded that I just shouldn't use the ext4 driver or convert my filesystem. I just re-installed my notebook with Ubuntu 9.04 and choose ext4. Don't really measure a difference, but I rarely use that machine.
For a benchmark of Ext4 in a variety of tasks/applications, see: http://www.phoronix.com/scan.php?page=article&item=ext4_benchmarks Usually the difference is there, but it's not big enough to "stick out."
