I noticed something very strange today. There was an Aperture update available via the Mac App Store, approx 600Mb. My MacBook had only just been booted up, so there was no chance that the update had loaded in the background on the computer, not even sure if the Mac App Store does that. Anyway, I clicked on the Update button and the 600MB downloaded in seconds at a very fast rate (50Mb per sec at least), far faster than any other downloads I have ever seen on my devices. The same thing happened with my iMac, booted it up, saw the update and downloaded in seconds (I am running Lion on both machines). The only change I have made recently is the installation of a new Airport Extreme basestation (the latest model). The speed increase cannot be due to the device just being faster as I will always be limited to my 20Mbps Cable download speed. The download should have taken at least 2 to 3 minutes but it was done in 5-10 seconds. Could this be due to some level of internal storage in the new AE, that can recognise that downloads are available and them in the background when they are released and then be ready when you need them? I know it was rumored that this would be a new feature but it was never mentioned by Apple when the new AEs were released. The 600MB Aperture download definatley did NOT download over the internet to both my devices when I clicked on the update, it was far too quick, nearly instant, it must have been downloaded to the AE.
