CDN Evaluation Criteria

A friend asked me about StyleFeeder‘s experience using CDNs, so I sent him the list of criteria that we use to evaluate the various content delivery networks that we have tried.  We’re currently using Akamai, Cloudfront and Panther for various types of content.  I’ve talked to pretty much everybody in the CDN space over the […]

About […]

DNS vendor performance

I came across this post about DNS performance on Hacker News yesterday, which was interesting because I’d been conducting similar experiments for StyleFeeder. Our site is fast and has scaled well, but I’m always on the lookout to shave off a few milliseconds here and there from our requests. I was looking at our Pingdom […]
