If you're looking for comparison numbers maybe look at: http://sebastian-bergmann.de/archives/745-Benchmark-of-PHP-Branc hes-3.0-through-5.3-CVS.html Just FYI, using ADODB will slow down the performance of your app. Any function calls cost against you and it all adds up. </snip> I have a copy of the files and database, but setting it up is not that simple. This vb.net is licensed and we don't have license for. If I could profile the app I'd be more than happy, but that's not going to happen anytime soon. Thanks for those numbers, they'll be handy :) ADODB removal will be studied, thanks for the hint!
