I did a simple comparison between Weka, RapidMiner and Knime - I did a model with 100 fold CV on dataset with a few thousands samples with 5NN classifier. Obtained results proofed that weka is the fastest tool (few seconds) Rapid Miner required few minutes, and Knime was the slowest (a few minutes). I've also compared it with Matlab Spider - I won't comment that results :).
