On specifically startup time for large files (narrow use case, but thats what we got), there's this comment from user jakear from a while back on an Atom 1.28 thread [1]: 1.1GB file, 10M lines. Code: ~10s, smooth scrolling, instant jumping. Sublime: ~50s, smooth scrolling, instant jumping. Atom: ~10s, smooth scrolling, very choppy jumping: ~5s loads per jump (also got some error messages about text too large for buffer) 1.0GB file, 40k lines. Code: ~15s, scrolling somewhat choppy, quick jumping Sublime: Application not responding after ~60s, waitied another 60s, no change. Same behavior each of the two times I attempted. Atom: ~8s, smooth scroll, ~30s per jump, occasional "Editor is taking too long to load" messages. Note: Atom enforces a maximum line length of ~500 chars before it wraps regardless of word wrap setting. This means the 8s load was only showing a couple lines worth of content. I find this restriction not acceptible for the long-line test case, but including anyways for completeness) Full "report": https://pastebin.com/wUv8PSgp https://pastebin.com/wUv8PSgp [1]: https://news.ycombinator.com/item?id=17369898 https://news.ycombinator.com/item?id=17369898
