I have a simple php script that builds an array, and then it print out the contents.  I have found that it takes about .3 - .4 seconds when I use ISAPI and only .003 seconds when I use CGI.  Is this an due to a change in IIS, or is this a PHP issue?  I have tried the latest build, and still get the same results.

It's normal.

In windows 2000 ISAPI was faster than CGI.  I would think storing a library in memory and calling it when needed would be faster than executing a CGI parser from disk per request.  Can you shed some light on to this?

We have a similar problem. It seems the output buffering don't work when running isapi on iis6.
Tried outputting (echo) 1000 "hello", 1.9 sek. Then tried outputting it with manually buffering output (ob_start()) , 0.6 sek.
Haven't tried cgi yet, it's next on our list but as Andy says, storing a lib in memory and calling it should be faster then calling cgi app every request. 

Platform: MS Windows 2003, IIS 6, PHP 4.3.2

To move around this problem, still using ISAPI on IIS6 you could put output_buffering = On in php.ini, if suitable for your application.
The comment in php.ini says it will slow things down, but in this case it's a huge performance improvement.
