Is the measurement influenced by caches and proxies?
YourSpeed uses a simple trick to circumvent caches, including remote caches such as proxy servers. A random string is added to the URL of every image. The cache will think it’s a different image and will fetch it again. There’s still the normal cache-overhead for storing the images and deleting old files, your harddisk is used exactly as if you were surfing by hand. Cleaning up the cache will temporarily increase your speed because the cache-overhead is reduced (no old files to be deleted). I can influence the measurement! YourSpeed is an accurate simulation of normal surfing behaviour. If you are running a heavy download in the background then your surfing speed will be lower and YourSpeed will correctly show this effect. At the bottom of the YourSpeed Explanation you will find a long list of things that will influence the measurement.
