Ranting aside, this seems like a valid complaint. Scaling and performance seem to be reasonably important in web applications, so why not write them in C? If the only complaint is the lack of good tools, why not build those tools? Disclaimer: I don't actually work on web apps, and therefore have no experience with these things.
But for most web apps, rendering HTML pages from script is not the bottleneck, it's the interaction with the database, and the solution is intelligent caching to reduce load on the database. The tools to mitigate these problems are already written in C (memcached, etc).
