The thread-safe version is designed for environments where the Web server core can keep the PHP engine in memory, running multiple treads of execution for different Web requests simultaneously. The architecture of IIS and the FastCGI extension provide an isolation model that keeps requests separate, removing the need for a thread-safe version.

As a result, there is a performance improvement on IIS when using the NTS version when compared to the tread-safe version because the NTS version avoids unnecessary thread-safety checks FastCGI ensures a single-threaded execution environment.
