Simple, for those who want a higher performance and have the system requirements ... PHP is the solution

.
Flat-Files databases can not handle big forums anymore.
So we've got two solutions:
1. PHP/SQL version
2. Perl/SQL version
I suggest that IP start developing a PHP version now and take their time finding the best ways to optimze the performance and remove security holes ... then - say after 6 months - they can release a final stable version of UBB/PHP.
Best Regards
