As the Three mobile network here still gives traffic priority over both HTTPS and port 8080, I tried some experimenting with HMA's VPN to see if I can exploit it. I never thought of bringing my laptop at work, so was limited to running the HMA App directly on the phone. After about 4pm, Three was giving a fairly steady 2.0Mbps to 2.5Mbps over HTTP and 4.5Mbps to 5Mbps over both HTTPS and port 8080 based on a series of TestMy tests. The following was an example about 4:30pm, HTTP vs Port 8080: I established a VPN connection to the HMA's Irish server and got about 3.5Mbps with the plain HTTP test. Based on past testing with HMA, its London server for some reason has lower latency than its Irish server, so connected to London and got a HTTPS-like speed test with the plain HTTP test. With multi-threaded tests over port 8080 (no VPN connection), I was able to get between 10Mbps to 12Mbps, 4 x 50MB tests in a row. The Speedtest App for some reason couldn't hit 10Mbps even after a few runs using Three's own Speedtest server. While privacy concious people generally avoid HMA due to its logging policy, the main reason I use it is for its flexibility of connecting to its servers, such as over UDP and even different port numbers. So if I remember to take my laptop the next day I'm in and get a chance, I'll try to see if there's a way of to exploit any extra bandwidth. I remember being able to get around 2Mbps from a 512Kbps limited hotel Wi-Fi connection using a UDP connection. The Android VPN functionality is fairly limited, e.g. fixed port, no UDP support, etc.
