I think Sublime Text, Atom and now also VS Code use Oniguruma as their regex engine. Atom and code even use the same implementation (node-oniguruma) and the syntax highlighting definitions for the languages are often also the same - because they were ported from TextMate to Sublime and then to Atom and Code. So even if the engine is not perfect and the defined regexes might not be optimal for some languages - it still would not explain why Atom is slower than Code. My personal guess is that is because Code might use a more stream-like processing of the source files and does not have the whole files in memory (it also works with really big files - which Atom does not support) and that this does work better |

You are probably right about the streaming system. It's interesting that atom doesn't do it that way (seeing as how streams are such an useful part of "server-side" javascript)
Like I said at one point i'd really like to dive into this stuff and spend some time trying to figure out exactly what the problem is (and maybe help find a way to fix it).
