[DUG] delphi is fast-very fast

HI all,

Just a quick note that if you use a PHP "accelerator", this caches the compiled PHP code ( NOT content!! ) on that server, and increases perceived performance by 4 - 10 times. That single fact plus the convenience of updating parts of the site had me leave ISAPI apps long ago.

cheers
