Since you already mentioned speedtest.net, and you may want a second opinion other than iperf, maybe you can download the free speedtest.net mini application, install it one one server each in Hong Kong and Manila, and then use it to measure traffic both ways, from a client in Hong Kong and then a client in Manila. However, you mentioned that you're getting much better results from your backup link. I presume you used the same test machines and iperf to test the backup link. In that case, it's not iperf we should be looking at as the culprit for giving you wrong results, but really the link. I recommend you contact your telco directly about this and be very transparent and blunt with them about the problem. Since you're paying for a premium service, you should be getting a decent service and shouldn't need to resort to trying to tweak things like the TCP window size and what not, just to get what you're already paying for to begin with.
