"[SOLVED] Pivot operation: RapidMiner vs Knime"
By using the surveys I thoutght that RapidMiner is better than Knime.
However, when I tryed to pivot a large amount of data (1.2 million lines that have the shape:transaction id, user id, quantity) knime did it in about 15 minutes and RapidMiner didn't manage to do it.
I specify that yes I used the last version of knime and the 5.3 verison of RapidMiner and the computer that was used for the benchmark had 8GB of memory and and i3 CPU.
I increased the memory for both (Knime and RapidMiner ) at 6 GB.
Since, normally (by using the surveys) RapidMiner is better than Knime, could you point out some tips to improve it's speed?
( because I'm starting to have doubts about the fact that RapidMiner is better than Knime)
