I recently started using FastCGI for PHP on IIS6 and am running into a problem with the CPU usage. This is a VMWare virtual machine but with a small number of hits on the sites the CPU usage of php-cgi.exe with spike to 100% and sit there for about 5 - 10 sec. This seems to happen about every 10 - 20 sec. Below is my the contents of my fcgiext.ini file:
[Types]
php=d:\Apps\PHP\PHP\php-cgi.exe
php:*=Wildcard
[d:\Apps\PHP\PHP\php-cgi.exe]
ExePath=d:\Apps\PHP\install\php-cgi.exe
Arguments=site1
QueueLength=1000
MaxInstances=20
InstanceMaxRequests=1000
IdelTimeout=200
ActivityTimeout=20
RequestTimeout=60
Any ideas on what might be causing this?
