User blog comment:AntiZig/Jungling Strategies for various champs/@comment-569195-20110401225338

Stonewall has a chart of all the junglers and rates for their different attributes. Speed is listed, goes from S(super) to A+,A,B ect....

Looks like karthus and Olaf are tide for 1st for speed.....Hmm really karthus. I guess Q spam plus that aura, if you can survive the hits you can probably take down the mobs pretty quick.
