we are talking about your whole stack, as you didn't ran benchmarks using
32bit php vs 64bit php.

yeah, using 32bit php should gain you a little bit performance gain, and
more stable and supported build.

how do you know that it is running faster? did you benchmarked it against
the 32bit version? I thought that you didn't.

yeah, life is a bitch.

are you sure?
I didn't really see any benchmarks supporting that fact, let alone for
windows, which is usually less of an interest for the apache httpd

yeah, if you are using php as an apache module, but if you use for example
fastcgi, you can run 32bit php with 64bit apache or vice versa.
