 **A:** A non-thread safe of PHP is recommended for use with IIS. Thread safety checks are not required, and you'll get a performance boost by not using a thread safe version. If possible, use a version compiled in VC9 instead of VC6. VC9 versions require you to have the [Microsoft 2008 C++ Runtime (x86)](http://www.microsoft.com/downloads/details.aspx?FamilyID=9B2DA534-3E03-4391-8A4D-074B9F2BC1BF) or the [Microsoft 2008 C++ Runtime (x64)](http://www.microsoft.com/downloads/details.aspx?familyid=bd2a6171-e2d6-4230-b809-9a8d7548c1b6&displaylang=en) installed
 
 You should also ensure you are using the latest version of the [Microsoft Drivers for PHP for SQL Server](http://www.microsoft.com/downloads/en/details.aspx?FamilyID=80E44913-24B4-4113-8807-CAAE6CF2CA05&displaylang=en) driver.
-If possible, you should also use PHP 5.4 which provides performance improvements over 5.2 and 5.3.
 
 Try increasing the IIS **MaxInstances** in IIS Manager > FastCGI from 4 to a higher value. For quad core CPUs, a higher value such as **32** should prove to provide a performance enhancement.
