Comment #5 on issue 1063 by [email protected]: Extremly slow save in RIDE 0.41

@björn:My guess is that it is somehow related to the structure of the data that is being saved.
As I can not access your data could you try to identify the part of the data that is the cause of this behavior?
For example bisect by removing randomly 50% of keywords / tests and trying to save.
