> In my statement I kind of assumed that all the "cheap" optimizations in the framework are already done (e.g. PHP APC cache is enabled, lazy classes/configs loading is implemented, etc.) so we compare "apples-to-apples": a highly optimized C++ framework to a highly optimized, say, PHP framework

I'm kind of skeptical, to be honest. I suspect a simple, unoptimized C++ application wouldn't have a lot of problems keeping up with a highly optimized PHP framework. Interpreters do so much extra work.

Not that I would use C++ for web stuff- that's 99% string munging, and string munging in C++ is how you wind up with your desperate last words mockingly quoted on seclists.org.

Assume your DB query takes 10 secs. It's irrelevant if C++ code takes 0.01 sec when your PHP code takes 0.1 sec.

Now why would I assume that? There are times when you need to generate a big report, and just the SQL can take that long or more. But typical web requests for typical applications are not like that. DB queries shouldn't take more than a couple hundred milliseconds for "typical" application requests.

Even counting that, the comparison is also not necessarily correct. In some cases, perhaps the C++ code would have taken 0.1s, where the ruby code takes 5s. In fact, 50x is about the slowdown you used to see for ruby in the programming languages shootout, and it is still pretty bad. [1]
