Yes.

Oh.

You probably want specific examples...

It really depends how you architect things in the first place...

If you built a Java app, and then converted it one-for-one to PHP,
performance would likely be abysmal, as they both take very different
approaches to development overall...

Without knowing more about your application, I guess I'd suggest you
start with callgrind (Linux) and see where all your time is getting
spent. Since Windows doesn't have callgrind, you'll have to find out
what it does have that's like callgrind, and use that, whatever it
is... Or switch to Linux, which might be easier anyway, and will
probably give you the biggest boost in performance.
