This time they added a configuration option for the large file warning threshold. This isn't enough.
Anyone else have the same problem?
I think the problem is simply that their stack handicaps them severely in this respect. I need my text editor to be able to handle large files and to be extremely fast.
The kind of files that choke Atom are large data files that there are usually better/different tools for, that have very different requirements from code editing. And that has little to do with the relative huge-ness of your projects.
It's already been proven that Javascript can be fast for this kind of thing. So there is something in the infrastructure that can be improved.
Last year I was working on a game demo under time constraints and to cut a corner I base64 encoded a bitmap font. Every time I opened that 32KB file it began to slow down because that one big line.
That being said I still use atom daily but not one big files or ones that contain big lines.
I've seen things like vim have problems with files like that, I think mostly from trying to syntax highlight the visible region.
When you need to edit data files or other huge files - don't use Atom.
