John Lim has made this new post over on PHPEVerywhere today concerning a separate project from his ADOdb - a "lite" client by the same name: ADOdb Lite.

ADOdb Lite was a result of a need for a very small, fast ADOdb library for a browser based game that a group of developers have been working on for over two years called Alien Assault Traders.

These developers noticed that the ADOdb package was consuming over 640k of RAM for each HTTP access. Currently, ADOdb Lite uses 80-85k of system RAM for each HTTP access. This is about an 87% smaller memory footprint. A side benefit is an increase in speed.

John didn't create ADOdb Lite, but he seems to support what they're working towards (and "respects their point of view"). He does comment, however, that their speed increase from the lower memory usage can be replecated with the regular ADOdb client as well...
