CacheFly CDN is the king (period) as hinted from CDN blog - CDN Planet :

Most CDNs have a initcwnd of 10. This is the default value in Linux kernel and apparently many CDNs have found this to work well. CacheFly, Highwinds, MaxCDN, ChinaCache, Akamai, Limelight and Level3 have a higher initwncd value. For some reason(s) they changed the setting and we are confident they did this for performance reasons. Internap has a slightly lower value of 9. And then there is Microsoft's libraries CDN (ajax.aspnetcdn.com): it sends two packets in the first round trip. That is ridiculously low and bad for performance. CacheFly's behavior is remarkable. The edge server sends out a very large burst of packets - 70. Our test machine advertised a receive window of 262144, so CacheFly clearly takes that into account. The test file was 100 KB and the 70 packets add up to that 100 KB. Note: the value for initcwnd is (obviously) not the only parameter that determines CDN performance. Don't think that CacheFly is the fastest CDN now globally, and Internap is the slowest. The initcwnd value is just *one* of the performance parameters and we believe it is good to know its value. |
