Scot Hacker's blog about the increasing amount of time it takes to rebuild his site, which has a large number of entries, points to scalability limitations using a system that builds static pages when compared to a server-side scripted system that builds pages as requested and then caches them. This, I guess, is one of the reasons I prefer PHP/MySQL apps like Drupal for a site that is meant to grow big (most blogs certainly fit that description) and prefer to only consider MT for smaller, brochure-ware type sites (AIfIA fits that description).

I'm wondering if SixApart is considering a solution -- especially for enterprise customers that might come looking -- that uses server side scripting to generate pages along this model rather than building static pages. I can imagine, with their Perl focus, that they would easily be able to modify MT use CGIs that generate and cache entries from the Berkeley DB or MySQL on the fly. Perhaps this is where SixApart will be going with MT Pro. Clearly there is a need for a version of MovableType that will let advanced users gain some advantage in terms of speediness.
