On the flipside, I recently had to make some changes to a ~1.5GB XML file, like in the middle of the file. I had a sudden flashback to the Atom editor, which developers considered a 1MB XML file as "large", and hence it totally chocked on a 100MB one I tried once, crashing out after eating 8+GB of RAM. To my mild surprise, it opened in a few seconds, and while all the fancy checking stuff got disabled, basic syntax highlighting still worked so element tags were colorized. Finding and changing the offending element was not much different from normal. I checked memory usage, expecting it to be astronomical, but it was quite within reason (~3 GB IIRC). I admit I did not expect it to go that well.
