I'm using external file hosting for about 22 semi-large products (160-560MB each). I've tested a few of the products to go through what has been described as a caching process on the E-Junkie servers.
The first time they downloaded (from my server) they were pretty quick (around 1MB/sec), but after waiting a while for the cache to sync to E-Junkie's s3 (so I've read), I'm now getting about 600KB/sec when a download starts, and then in 7 out of 10 download attempts (after the caching), the files have slowed WAY down - sometimes to 20KB/sec, and then they have totally hung without completing.
During at least 2 of these attempts, I've opened up speedtest.net to rule out my local connection, and I'm consistently getting around 20MB/sec, so it's not on my end. I'm preparing to launch a fairly large music licensing service and if these are typical results, I'm done before I've even started.
Can anyone speak about their experience using large externally-hosted files and if this has been a problem before, or if you're having any problems now (hoping that this is just a temporary glitch, but it has been going on for at least 12 hours now).
I had hoped to launch my site tonight, but now I'm waiting...
