A bit of research reveals that it uses EdgeCast’s infrastructure, one of the largest players on the CDN market. On a side note, it’s not so strange that Media Temple’s CDN is performing so well. If you strictly want to reach a North American audience, however, it’s on par with Google’s CDN. It’s more than twice as slow as the other two CDNs in Europe. #DOWNLOAD LATEST JQUERY FROM GOOGLE DOWNLOAD#The worst performer: Microsoft’s CDN had the slowest average download times in this survey, and if you want an optimal experience for European site visitors we can’t recommend it.Media Temple’s CDN doesn’t support HTTPS. For sites that use HTTPS: Google’s CDN is clearly the faster option in Europe, but in North America it’s pretty much a tie between Google’s and Microsoft’s CDNs.Google’s is a close second in Europe, but lags behind significantly in North America. For sites that don’t use HTTPS: Media Temple’s CDN is hands down the fastest in both Europe and North America.With those results presented, here are our findings: one test per minute for 30 days.) The verdict on CDN performance These averages are based on 43,200 tests per CDN per connection type, which as you can imagine is a good-sized sample. For the performance part of this survey we chose to focus on recent results instead of the entire year, since it’s how fast these CDNs are now that matters, not how they were performing months ago. Here below are the average load times for all three CDNs for a 30-day period (June 16 – July 16). This is because performance differs depending on what kind of connection users make (HTTP or HTTPS/SSL) and the location they are making it from. Do visitors access the site over HTTPS/SSL or regular HTTP?.Where are the bulk of a site’s visitors coming from?.The answer to that is, “it depends.” There are a couple of things to keep in mind: We will focus the rest of this article on performance since that is where the true differences are. You shouldn’t have to worry about it working or not, and the distributed nature of a CDN usually makes it extremely reliable, as this survey shows. All three had, when rounded to two decimals, 100.00% uptime. The only CDN with any downtime at all for this entire year so far was Microsoft’s, and that was just a few minutes. Reliability is stellar for all three CDNsįirst off, all three CDNs proved to have excellent availability. Tests were performed from multiple locations spread over Europe and North America, once per minute around the clock. We used our own site monitoring service ( Pingdom) to examine both uptime and download performance. We also differentiated between HTTP and HTTPS connections, since there can be a big performance hit when using SSL. We downloaded the minified, gzip-compressed versions of the jQuery file, just like a web browser would. Since web browsers will generally send requests that ask for gzipped results if there are any, that’s what we focused on. It can be seen as a general comparison between these three CDNs since the results should apply to any files hosted on them. Worth noting is that this survey isn’t necessarily specific to which CDN is best for jQuery. Media Temple’s ProCDN (the official “jQuery CDN”)įor the sake of simplicity and symmetry, we’ll call these three CDNs the Google CDN, Microsoft CDN and Media Temple CDN for the rest of this article. #DOWNLOAD LATEST JQUERY FROM GOOGLE FREE#There are three CDNs available that host the jQuery library free of charge: This survey will hopefully answer that question for you. Which one offers the most reliable file hosting and the best performance for end users? With that established, the question then becomes which CDN is best for jQuery. So in other words, it’s usually a good idea to use one. There are other ways using a CDN can help performance as well.
