Bug 351846

When changing the column-sizes in dolphins detail-view (e.g. the "Filename" or "Size"-columns) dolphin only reacts very slow.

If you open dolphin from a terminal and you resize the columns, the line
org.kde.dolphin: Saving view-properties to "/home/[username]/[foldername]"
gets printed many times while changing the width (where [username] is my username and [foldername] is the name of the directory for which I change the column-width).

And yes: the option for storing the view for each folder separately is activated. I'm not sure, if this option affects this behaviour. Switching it of does not solve this problem for me, but in the arch-forum someone reports that he does not have this problem and he turned this option off.
(Link: https://bbs.archlinux.org/viewtopic.php?id=201550)

The Version is 15.08.0 (which can not be selected in the version-select-box)

Reproducible: Always

Steps to Reproduce:
1. Open dolphin
2. Switch the view to "detail-view"
3. Activate the option, for saving the view for each folder separately (perhaps not necessary)
4. Change the size of any of the columns

Actual Results:  
The resize-action is very slow, probably because the new column-size is saved many times, while still resizing the column.

Expected Results:  
The resize-action should be much faster. Probably it would make sense, to only save the new column-width, when the resizing is done (don't know the technical details/internals though).
