File managers very slow in large folders

Post by RSanders » Sat Feb 17, 2018 1:16 am

I have Linux Mint 18 installed and and up-to-date and have been using Mate desktop. I have a NAS partition with 2500+ video files on it. When I select this partition it takes the file manager 15-20 seconds to respond. I have tried Cinnamon desktop and many different file managers, specifically, Dolphin. Nautilus, Nemo, PCmanFM, Thunar, Caja, and Midnight Commander. They are all very slow. I love Mint except for this annoyance. I am able to dual boot through a boot manager called Boot It Bare Metal from Terabyte Unlimited and I have an up-to-date copy of Windows 10 on my HD. Windows 10 responds to this partition in 1-2 seconds. Is this something I have to live with ... or is there another solution? Thank you in advance for considering this question.

I have this problem also, and others have reported it. As I understand it, the issue is with creating thumbnails of all those files. I went looking for a solution some time back, and it seems like the answer was to disable the thumbnailer, or maybe to use a different thumbnailer. But I lost interest before I solved the problem on my computer and am currently just putting up with it. Anyway, a forums search for 'thumbnail' or 'thumbnailer' might turn up some help for you.

For Cinnamon / Nemo ensure that any unused plugins are disabled. Access the plugin settings via keyboard shortcut <Alt-P> from within Nemo

In particular the default ChangeColorFolder+NemoPython extension can cause slow-down.

if in doubt disable all the extensions and see if it improves /solves the problem. Then add them back in one by one testing response as you go or as and when you realise you are missing functionality you use.
