Most likely because this is and was always kind of superstition. ;)
An almost full filesystems has to do more to find free space, but I don't dare to
give rules of thumb.
> I was wondering, is there a known point in UBIFS (or ext4), where leaving less free storage space, that performance is dropping? Maybe a ratio of free-occupied is not the right way to look at it, but to leave a certain size free (e.g. 50MB)?
I don't think so. Maybe Ted can give you more details on ext4.
For UBIFS I'd say, figure yourself. i.e. run benchmarks...
Thanks,
