In the midst of all the controversy, Royal Pingdom decided to contact a test over the past 30 days to put nine URL shortening services through their paces. After all, you want more than just brevity in a URL shortener - speed and reliability are also important factors.
Well, it turns out that Tr.im isn't even the best URL shortener hailing from Vancouver. Pingdom tested two things: the average time it took each service to load a page (overhead) and its uptime. The fastest service was actually Is.gd (with an average load time of 163 milliseconds), followed by bit.ly (261 milliseconds) and in third was Vancouver's ow.ly (289 milliseconds).
Tr.im ended up being the third slowest and losing out to ow.ly for uptime as well. When both the reliability and speed rankings are combined, ow.ly and bit.ly tied for first place overall.
