It's really slow when copying files, exactly in any filesystem, compare with KDE, I hope it's not my delusion.

https://bugzilla.novell.com/show_bug.cgi?id=224527 ------- Comment #7 from linux@51sun.cn 2007-01-29 11:23 MST ------- No, we shouldn't. :) Somebody posted a report to gnome, I think it's really a problem that posix_fadvise() which was called by modules/file-method.c wastes too much time, isn't it. I think it's useless. may be posix_fadvise() have poor implement for some filesystem. I have taken some test at XFS and ReiserFS, posix_fadvise() does occupy 88.82%-99% time in XFS(wasted much), and 10% time in ReiserFS(wasted fewer), and DEBUG_PRINT(never need) 2%+-(wasted fewest but time was wasted!). Then I try to comment// the syscall and repackage it, it's as fast as KDE. I think fadvise() is useless. Quote Programmer's Manual: it merely constitutes an expectation on behalf of the application.

Could you get me a sysprof of the slow copy operation? 1. Install package "sysprof". 2. Install package "sysprof-kmp-default" (or whichever is good for your kernel). 3. Stop all unnecessary programs, as they can make the trace unclear. 4. > sudo /sbin/modprobe sysprof 5. > sysprof 6. Start copying the file. 7. Hit the "play" button in sysprof. 8. Wait 10-30 seconds while copying. 9. Hit the "report" button in sysprof. 10. Save the report to a file and attach it to this bug.

I see that we're calling it very frequently (once per read plus once per write, or about once for every 4KB transferred). It would be better (and not much harder) to reduce the number of calls to gnome_vfs_forget_cache() in gnome-vfs-xfer.c:copy_file_data(). However, I don't know if the overhead is per-call or per-cache-block, and I don't have an XFS filesystem to test on easily. I've elaborated a patch to test the hypothesis.
