I have more info. I have tested the disk with other file managers, dolphin, and others, and isolated performance problems to nautilus. They have to do with changes to NTFS, file moves, deleting dirs, going to the contained dir. I have used thumbnails and icons with this file manager and expected some delays because of the disk, but since the upgrade, the performance hits are far worse.
I have noticed that the changes happen OK in groups of three or four then the file manager hangs for a minute or two and returns eventually. Sometimes I find that it is better to kill all the open windows and wait, and sometimes when I do this to test if I have access to the disk with another file manager or from the shell, I do. I can reopen the file manager and still see a spinner after that, even on a disk attached directly to the system, not on a USB port. This is the evidence I have that the problem in with nautilus. I don't want to give up nautilus because when I am moving images it shows you thumbnails of duplicates by name to see if they have the same visual content. Other file managers will clobber duplicate files by name without this check. I know there is overhead in doing thumbnails. I expect that, but the performance seems to have deteriorated since in the upgraded version. I have reported in the past, deadlocks between identical file requests that the program forks without checking and caused by user impatience, and now performance hits on valid file operations. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/709935 Title: File MGR is very slow on any type fs -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
