I did some consulting a few months ago. A FOAF had developed and launched a quite comprehensive online textbook, and their success was choking the the website. They don't know much programming, and had they not used a framework (and one of the slower ones at that), they wouldn't have launched. Period.<p>I moved in, got them off shared hosting, replaced the built-in search with a Apache Solr, tuned the cache and a few other quick wins, took my money and left them my phonenumber. They live to fight another year or two, and I'll stop by and help again then.<p>Scalability is not your problem, getting people to give a shit is.<p><a href="http://teddziuba.com/2008/04/im-going-to-scale-my-foot-up-y.html" rel="nofollow">http://teddziuba.com/2008/04/im-going-to-scale-my-foot-up-y....</a><p>Frameworks helps getting people to give a shit, custom C++ extensions doesn't, so use a framework, unless Yahoo! called.
