I witnessed that deleting directories (with the size of a couple of gigabytes) which contain many files is very slow when using rm. It takes up to several minutes!
When deleting the same folder via the File Manager, the job is done within a second. (It takes another second to empty the trash afterwards.)
What is the reason for this?
rm
had to load everything from disk but the file manager did everything in memory, that would explain the difference.rm
does. AFAIK file-managers just userm
in the background.
