I found MaxCDN unworkable due to the fact that I have DEEP visits (only 10% to home page, 90% to over 2000 other pages daily).

Vincej,

1. How long did you stay with MaxCDN?
2. What was your cache-to-hit ratio at the end?
3. How long was your maxage/expires?

I think if you set your maxage/expires long, lets say 1 year, for your images, css, and js, over time you would reach better than 90% cache-to-hit ratio.

We did some tests on on what TCP factors(scroll down to "Content Delivery Networks and big sites" section) effect pageload and how CDNs have set them currently.

Basically most CDNs have a very low receive window and they make a new connection to your server for each request, which makes cache MISS expensive.

If you anticipate a lot of cache MISS, then i suggest using fastly AFAIK they do connection pooling and some protocol level optimizations. A cache miss seemed to not have much overhead compared to going direct to origin...
