I assumed this would be the preferred way to run php, although I never really
looked into cgi/fastcgi.
I also have not tried using php with IIS.
We are considering using the windows version of Zend Performance Suite.
It seemed to us to be easiest and fastest solution. Although it is currently not available, I was apparantly lucky enough to be able to download an evaluation version of it. And it does improve performance a lot. I still have to ask Zend if/when the windows version will be available again.
