only thing I can see this changing is your response time to a ping. Can't change the real amount of time it takes.
Edit: andddd I read this
WARNING! This paragraph will be the only one that contains technical content! Faster Ping works by removing the acknowledgment delay from TCP packets. This delay happens inside the kernel's TCP stack, and is a necessity for a lot of functions that go on inside a TCP stack. The other modification Faster Ping does is to remove delay in sending small packets (think anything less than a dozen or so bytes). These changes, at least theoretically, should not impact system stability if the Windows kernel has proper TCP/IP stack implementation. Okay, end technical content.
