Slow CDN requests
We have noticed CDN requests as being weirdly slow on webpagetest.org (public site). Here is our test with webpagetest:
http://www.webpagetest.org/result/120717...1/details/ and the same thing with pingdom: http://tools.pingdom.com/fpt/#!/7qfgx6RN...hebest.com

Any ideas?

RE: Slow CDN requests
You are basically seeing what happens when you are bandwidth constrained and the different resources are all downloading over the same 1.5Mbps connection at the same time. The pingdom tests are run on a native datacenter connection (100Mbps or 1000Mbps) with minimal latency and last time I checked it used a custom browser emulator.

Here is the same test without the traffic shaping to a consumer DSL connection: http://www.webpagetest.org/result/120717_BH_W8M/

Thanks,
