Bug 215953

Version:            (using KDE 4.3.3)
Compiler:          gcc-4.2.4 
OS:                Linux
Installed from:    Gentoo Packages

I regulary use NFS/SMB shares mounted via VPN hostet by my company. I use DSL connection which means it is a slow connection compared to LAN.

On such directories Dolphin performs _very_ poor. Directories with several hundred of files/directories let dolphin freeze for several seconds. Scrolling in such diretories also makes dolphin very slow. There is no smooth and no fun in working with such diretories with dolphin.

From my understanding this is realted to the fact that dolphin determine the filetype by reading the header of every file which ends in massive (more or less) useless calls over a slow wire and slowing all down. Further more dolphin entering each directory in the current directory to count the files in it to display the "size" of this directory. Nice feature for local browsing - but horror for remote browsing.

My suggestion is to change the behavior of dolphin for remote shares in a way to greatly improve the performance for those directories:
- Disable the "count files for subfolder"-Feature for such shares and
- Determine the filetype by its suffix and not by reading the header. I know that this is a nice feature for local files and that unix tends to not use file suffixes at all - but IMHO not at the cost of such massive performance casualties

I observed this problem with KDE 3.x too (using konqueror) but hoped that dolphin gets more "intelligence" for such situations. But unfortunately nothing changed which leads me to open this wish now.
