[SOLVED] Same workflows differ in run time

fras

Hi,
I’m playing around with a performance work flow just mentioned in the seminar last week
(thank again for this nice seminar).
I drastically reduced this work flow cutting “Loop Parameters” and “X-Validation” so I left
with “Retrieve” and “Decision Tree”. But running this one it never returns within minutes.
BUT if I create this work flow from scratch it finishes in one second and switches to the result
perspective. I attached these two work flows for further investigations.
Thanks in advance,
Frank

Hi Frank,

nice to hear the you are actually continuing on experimenting with RapidMiner. This is a problem which also occured during the seminars, and we have an item on our TODO list to fix it.
You added (probably by accident) a breakpoint to the root operator. You'll easily see it, if you open the Tree view (e.g. via View -> Show View -> Tree). To remove it, click somewhere onto an empty space in your process, then right-click and remove the breakpoint.

Best, Marius
