Well, an order of magnitude means we can do the same
amount of work with
half the machines we have now, or twice as much with the same. That's a
pretty big deal. That said, rewriting the entire codebase in C/C++ will
take a huge amount of developer time. If there are any time-sensitive
spots in the code, it might be worth recoding those in C/C++ - but I
don't know about the entire codebase. I really don't think that's a
"win", as far as developer time, or future maintainability.
Is it possible to write part of a single page PHP program in C++? Or do you
have to make the entire page into a CGI?
I've got a lot of C++ experience, but very little PHP. I suspect that there
are a lot more C++ programmers than PHP programmers out there, and we like
to help. :-)
