Nobody can answer that with absoloute certainty since nobody has tested the top running speed of every known species of spider under similar conditions. However, one of the fastest Spiders that have been clocked is the Giant House spider (Eratigena sp., (formerly Tegenaria duellica/ T. gigantia). It managed 1.73 feet per second over a level surface, though it can only manage this speed in short bursts before it has to stop to regain energy.
Tales of camel spiders achieving speeds of 35-40mph are wrong on two counts; Firstly, camel spiders are not actually spiders but a seperate order of (ten-legged) arachnid known as Solifugae, which are more closely related to scorpions (wind scorpion is their other common name). Secondly, wind scorpions/camel spiders can only manage a top speed of around 10mph across flat terrain. While still very fast, it's way short of the 35-40mph stated on some internet sites.
Unfortunately there are numerous urban myths about camel spiders that were based on anecdotal tales told by GI's returning from Iraq and Afghanistan which were clearly intended to scare new recruits, but which quickly spread via the internet, leading to many common misconceptions about them persisting to this day.
In absolute terms, the fastest spider is the camel spider that lives in hot, desert regions. This eight-legged speedster can run across sand at an impressive 30 - 40 mph.
