I'm not sure if it's just my location, or where you host, or some other routing issue. But I find downloading the EAPs to much slower than I would normally expect. This latest EAP is coming through at 20kB/s which is unfortunately common. I also downloaded the latest Sparrow Mail client beta and that came down at 400kB/s. I'm not sure of the costs of hosting on a CDN, but it is something that I would consider.
