As I'm staying in Chiang Mai at present, I've decided to start speedtesting various cafes that I'm working from.
Tests were run using Speedtest and some can be seen at the link.
Tests were conducted in pretty average conditions, hopefully simulating average working conditions. Speeds may vary due to time of day, busyness and other factors, but I hope this helps to give a rough estimate.
See results below.
