rackspacecloud.com’s Cloud Files network benchmark

I got a rough benchmark.
Main purpose is to know how Cloud Files(rackspacecloud.com) is fast from Tokyo, Japan. Also I compared the speed with Amazon EC2/CloudFront and Sakura Internet 7,800yen dedicated hosting service.

2135 (cdn.cloudfiles.rackspacecloud.com)
42 (rackspacecloud cloud server mem 256M)

@San Jose, CA (3.2Mb/s by speedtest.net)

304 (sakura internet 7800yen server)
2058 (cdn.cloudfiles.rackspacecloud.com)

@Tokyo, Japan (35.4Mb/s by speedtest.net)

Cloud File is pretty good. Indeed, Cloud Servers plan is good at low-end scale-up. Never change its IP to resize 256M memory to 512M. There is a down time like a couple of minutes. Unfortunately, DirectoryIndex (like index.html) doesn’t work on Cloud Files just like S3/CloudFront.
