My biggest objection to Atom over Sublime is the memory overhead when opening even moderately large files.<p>I&#x27;m in ops rather than dev, so often deal with 10mb+ log files - but don&#x27;t have a lot of the IDE type requirements of my colleagues. Sublime open them in seconds and is nice and quick to search through and look at. Trying to open a 10mb file in atom causes it to chew up 1.2gb of ram and it&#x27;s laggy when scrolling nevermind when trying to search etc.<p>Sublime on the other hand not only starts up quicker and is more responsive, but it&#x27;s only costing me 100mb of ram for my 10mb file as well as 20 others I&#x27;ve not bothered closing.<p>If I try and load a 100mb file in sublime it doesn&#x27;t balk. Takes about 8 seconds to load, but once loaded it&#x27;s amazingly responsive (to the point where I thought I still had my 10mb not 100mb file loaded). Atom attempts to open the file but takes forever and then dies after exhausting the 8gb ram on my laptop.<p>tldr: sublime feels stable, lean and fast vs memory munching and perceivably slow.<p>Edit: oh, and atom&#x27;s installer is 104mb, the new build of sublime3 is 8mb.<p>edit2: Even after a clean boot atom just crashes trying to open a large file well before it fills up my memory, so no idea.
