I have a server located in the Netherlands also targeted at The Netherlands. To reduce load on the server I tried to use MaxCDN for serving static content like images.
I am webpagetesting my site on a regular basis from the Amsterdam Webpagetest.org location. Quite often I get results like this one: http://screencast.com/t/MWYyNDMyNm
The initial connection or TTFB to the CDN sometimes take many seconds.
Here is a graph of my webpagetest.org results for the past days: http://screencast.com/t/YWQ4ZTNiMGE All the high peaks are caused by loading times of static CDN content.
Does anyone else experience this problem? And more important; how can I fix this? Could this be caused by MaxCDN or the load/connection speed of Webpagetest.org itself?
Have you tried from different test locations? I haven’t seen that kind of behavior with MaxCDN in my testing but I haven’t done a lot of testing against their Amsterdam agent either.
