<p dir="auto">So, I use my text editor for all kinds of things (writing code, reading readmes, editing dotfiles, etc). One of the things I do most often during any given day is open up large log files to troubleshoot Enterprise problems. These files can sometimes get as large as 500-800MB.</p>
<p dir="auto">I just tried viewing a 350MB log file and Atom locked up immediately -- the file selector didn't change and the entire window went completely white 4 seconds after I tried viewing the file. I could still close the top level window, but we should still have better handling for this kind of thing.</p>
<p dir="auto">Sublime Text 2 took about 55 seconds to open the file, but gave a nice progress indicator while it was loading:</p>

<p dir="auto">Once it loaded it was as responsive as any other file I load (scrolled fast, normal text highlight performance, etc). It would be nice if we set this as a baseline for expected behavior (progress bar + responsive after loading).</p>
