My first reaction to this was what thinking this sounded like something out of the mouth of Cliff Clavin. I mean, how can a piece of software impact something that is mainly due to physical limits? Well, after thinking about it for a bit, and reading up on what the tool does, it can.
WARNING! This paragraph will be the only one that contains technical content! Faster Ping works by removing the acknowledgement 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.
Faster Ping does work to reduce the ping time seen in World of Warcraft and other MMORPGS. The technology behind it makes sense over all. However, there is a dangerous flip side: it will slow down your normal, every day web browsing. On my computer, I noticed a slow down of about 10% to 15% while browsing sites like WoW Insider and Google, and only a decrease of about 2% in my ping rate while playing WoW.
So what's the verdict? Is Faster Ping worth it? If you read the technical paragraph, you'd have noticed that I said the changes faster ping makes are theoretically okay. But as we've all learned over the past few years, just because something should be good does not always mean it is good.
I recommend that you do not use Faster Ping on anything that has important stuff, besides WoW, on it. If you're lucky enough to just have a dedicated gaming computer, great. Put it on it and use it. However I would think twice before using it on a computer with all your college course work or financial data.
What do you think of Faster Ping? Have you used this tool yet?
