How to view and edit large delimiter separated value files?

I have been using csv-mode to modify small to medium sized CSV files, but recently I have been working with large files containing more than 40,812 entries. csv-mode struggles to align and navigate the tables, and is too slow to be usable as is. In…

Batch loading binary files

Improve emacs performance when working on large files

I'm a former vim user that switched to emacs + evil with a still relatively simple configuration with only 36 packages. I'm really happy with the additional functionality emacs delivers, but one thing bothers me really much. Emacs is much slower…

Visual clutter on the left edge

I am not sure which terms to search for this with, perhaps you can help. Sometimes when I move around my emacs window, some grey clutter emerges on the left hand side. The file that I am working on is growing in size (82 Kb), but is not that huge (I…

I have org-mode files about 50K lines long, which I can edit and save file; but once in a while accidentally marked a large region by typing C-x C-x or C-x h, and copied too much data into clipboard, so Emacs hangs until killed by oom. Is there a…

docview: suppress "File X is too large, really open?" confirmation

Is it possible to avoid the "File X is too large, really open?" confirmation? If not, would it be possible for Emacs to remember my answer the first time I visited a large file? If I visited it once, I will surely want to really visit it again.
