We use LoaderMax in our Facebook game to handle downloading of all files from an Amazon CloudFront CDN. During the initial load, we download about 15 .zip files and extract them once downloaded.
We have maxconnections set to 100 (I'm aware that's unlikely to ever happen), and for the most part, the zip files are downloaded simultaneously and quickly, in about 15 seconds.
We are having a fairly large number of users report load times of > 3 minutes. I've started logging this, and it does appear that the zip files take that amount of time to download for some users. We have managed to recreate this on one of our staffs home machines, consistently. It appears that it is only downloading one zip file at a time, then waiting 5-10 seconds before downloading the next one. Pending further investigation, I wanted to ask if there is anything obvious that anyone would know that could be causing this, or if anyone has experienced this issue before?
