True, but I think his post isn't about generalized comparison of programming languages, but rather a pun towards "Its faster because its C" claims. Not that often our software can benefit from exploiting caching, especially in "release often, release early" world of web startups.

Not sure you're following: C programs can be optimized to take advantage of caching (or to use a low-overhead allocator, or to use more or less compact representations) in ways high-level languages either retard or disallow altogether. And all software benefits from caching.

I think your real observation is that C level performance just isn't that relevant in scale-horizontal network-bound programs, and I agree with you.
