There is a performance hit in using the cgi - but as this is involved in
starting up and shutting down php.exe, the more complex your script are, the
less noticeable is the performance degradation. I've been using PHP as a cgi
on production NT boxes for 18 months without any problems, but I guess the
traffic on these boxes would be regarded as moderate (30000 page impressions
per day, all generated by PHP?MySQL or cgi stuff I wrote in C).
Because IIS is a multi threaded server there are issues regarding the thread
safety of some bits of PHP code. Much work has already been done to fix
things but it is seriously hard stuff to debug, and there are clearly still
issues which need fixing - I only we could find them!
