If you are here by Twitter, post the page may have been charged nearly 2 seconds slower than if you had accessed pear URL own the our site. This is one of the conclusions which there came a research initiated by WatchMouse company, which measured the reliability of shortening URLs in web services.

The company monitored 14 shorteners services most used during the course of the month, measured every five minutes on any of your servers in the world how long each service takes to redirect the user to a page. Keep in mind that they did not measure how long it took to open page, only the redirect.

The research concluded that the fastest redirectors are Goo.gl and Youtube, both controlled by Google, which generate a maximum delay of just over 320 milliseconds. The slower was the Fb.me used by Facebook, which can guarantee up to more than 2 seconds lost in the user navigation. On the uptime of the servers, only the goo.gl and twit.tl (the latter administered by Twitter) remained in the air for 100% of the monitored time. The least reliable was the Snurl.com, which was down over 2% of the time it was tested.

In general, WatchMouse says shorteners leave the web slower and can expose you to malicious links more easily. However, they bring advantages such as the possibility of tracking the click statistics. It is to the user to decide whether the change is worthwhile.
