Starhub are still throttling international traffic on port 80 - and here’s the proof. Downloading the same file, from the same server, at the same time, is nine times faster if you do it on a port other than port 80.
I tested with a ten-megabyte file of random junk. At full speed, the download took one minute and six seconds; on port 80, it took nine minutes and fifty seconds.
I’m going to have to set up a proxy server in the USA to get the performance that I’m paying for.
