Open Source Highlight: namebench
- by eddraper
DNS is a big deal. Even small incremental changes to improve its performance can yield significant value due to the vast quantity of look-ups required when using the internet. Until now, It’s always been one of those things I had to kinda take on faith… was my ISP doing a good job? Are those public DNS server really that much faster? What about security and privacy concerns? Let me introduce you to namebench. This is the kinda tool I really love – one that immediately delivers value and is almost over-the-top OCD in its attention to detail. Trust me, this tool is utterly ruthless in it’s quest for getting it right – you’re not left with a big question mark after it presents its data. The results are conclusive and actionable. Here’s what is does: It hunts down the fastest DNS servers from your desktop that it can find using thousands of requests. No, it doesn’t pop up this little dialog in 10 seconds to give you some “off the cuff” answer from a handful of providers. It takes the better part of 10-15 minutes to run. When it finishes, it presents you with a veritable horn-o-plenty of data. Mean response duration, response distribution, bad data, no stone is left un-turned. Check it out. You’ll dig it.
