CDN Performance Report
Each month CloudTweaks will be providing a series of benchmark testing performance reports conducted by our contributing partners. The first in our series will be on (CDN) Content Delivery Networks which is a growing industry whose customers are primarily web based companies looking for that extra layer of site protection and speed. This monthly Performance Data Report is provided by Cedexis.
In North America we note an increase in Latency for Akamai around the 14th of June that lasted about 3 days. Over the course of the month however, Akamai maintained a clear advantage over the other CDNs measured here.
Moving to South America we see that Akamai is also maintaining a clear latency lead at 125ms on average for the month vs. their competitors as measured at the 75th percentile.
In Europe Level3 and Edgecast ran neck and neck for the entire month at the number 2 slot averaging roughly 67ms at the 75th percentile.
In Asia Akamai ran on average at around half the latency of its nearest competitors at around 37ms at the 75th percentile. Of note was a 3-4 day increase in latency that knocked them to over 160ms for at least 2 days on average.
In Africa Akamai ran at near 210ms at 75th percentile while the rest of the pack at between 247ms and 251ms at the 75th percentile.
Now turning our attention to Availability we see that worldwide (5 major geographies: Asia/Europe/N America/S American/Africa) for the month of June Availability on average was between 98.295% and 98.578%. In spite of a significant dip in Availability for Level3 in the middle of the month – they led on average for the month.
Regionally the story was different. It was only in Europe that all 5 CDNs reached 99% available. In N American not one CDN was over 99% for the month. Other geographies were worse.
