I had a gig which required opening ridiculously large XML files (metadata for music albums). Some classical music compilations (think "6 CD bargain bin" boxsets) would end up with 1-2GB XML files.
Sublime didn't even flinch when opening and navigating around the file. Truly impressive text editor and absolutely worth the license cost.
2.5G is definitely excessive.
Not optimized, perhaps, but not unreasonable given the metadata over a nearly-500MB file I would think?

Not sure how it represents text, but if it's using UTF-16 (I'm on Windows), then that's 900MB just there given the ASCII input file.
Not gonna say it's lightweight, but not excessive in my book.
I recall trying Atom before VSCode had been released. I loaded up a 1MB XML file and it ground to a halt.
After some searching I found a bug tracker issue reflecting this, where one of the devs said something to the effect of "a 1MB XML file is extremely large, I don't think we'll support that".
At that point I uninstalled Atom.
On a related note, not long ago I accidentally dragged a 450MB SQL script into VSCode. I fully expected it to cave like Atom had on the 1MB XML. However to my pleasant surprise it worked just fine. Editing it was as quick as a regular file, and the memory usage was not excessive (around 2.5G total). I admit I was a bit impressed by that.
