Fix Naultilus slow loading some directories.
If nautilus is taking an age to load some directories on your computer then you may have Assistive Technologies enabled.
Simply go to the System menu on your desktop and then in Preferences. Click on Assistive Technologies.Untick the box marked "Enable Assistive Technologies" and choose "Close and Log Out" at the bottom of the window.
When you log back in Nautilus should be opening directories instantly again. Apparently this became an issue in 8.10 when Assistive technologies was enabled by default, I only spent aoround 8 months suffering with this before getting off my backside and finding a fix, it is disappointing that there has not been a direct update to sort this out, there must be a lot of people stuck with this problem.
