Atom could not keep syntax highlighting when openning the “100k lines” file.Visual Studio Code did not allow me to open “10m lines” file saying “very large”.Atom could not open “1m lines” file and reported “crashed” after around 40 seconds.TextEdit has a pop-up animation when opening a window, which slows it down a little bit.TextEdit does not open a edit window when launching, instead it shows a file picker window.The file used was the 370KB one in “Files Open Time” tests. I used Activity Monitor to add up memory used by all its processes. String = 'abcdefghijklmnopqrstuvwxyz1234567890\n'Įach editor was launched first with a file loaded. The files’ sizes were 370KB, 3.7MB, 37MB and 370MB respectively. Files Generatingįour files contained 10k, 100k, 1m, 10m lines were generated by the following Python script.
ATOM VS VISUAL STUDIO CODE FULL
I recorded the time between the file being released and the moment when the file was full loaded. A file was dragged from Finder to its window. Files Open TimeĮach editor was launched first with a window open. I would record the time between clicking the “New Window” from the menu in the Dock (or its equivalents) and the moment when first window was full loaded. Window Open TimeĮach editor was launched first with all windows closed afterwards. I recorded the time between clicking the icon and the moment when first window was full loaded. Launch TimeĮach editor was launched from Dock by clicking the icon. macOS’s stock TextEdit was used as a reference. All programs I could see had been closed.
ATOM VS VISUAL STUDIO CODE PRO
The hardware I tested on was a MacBook Pro 2016 13-inch with Touch Bar (with 2.9 GHz Intel Core i5 CPU and 8 GB 2133 MHz LPDDR3 RAM running macOS Sierra 10.12.2). So I want to do a test and find out their performance difference. Visual Studio is also built using Web Technology like Atom, but reviewers said it is faster. These days, I Googled “Sublime Text vs Atom 2016”, trying to see if Atom has significant improvement when I found Visual Studio Code.

The reason I sticked with Sublime Text was performance: Atom was slow, even after when Atom 1.0 was announced. I tried Atom one or two year ago and I was impressed by its active community (GitHub! I love GitHub). Speaking of text editor, I have been using Sublime Text for around 3 years, and I have no issues with it.
