I continue to want to like Atom, and I try it out several times a year. Just updated, and see that it still has big performance problems on my system. I currently have BBEdit and SublimeText open for real work, and these are apps the have been running for days.
Here 100% would represent full usage of a CPU core:
BBEdit:
15 files open (various types/sizes)
76MB RAM
< 2% CPU
1 process
25MB app disk space
SublimeText:
10 files open (various types/sizes)
169 RAM
< 2% CPU
1 process
27MB app disk space
Atom
1 small Markdown file open
> 1.2GB RAM !!!!!!
> 85% CPU
7 processes
205MB app disk space
Just sitting in the background I am seeing Atom's CPU and RAM usages fluctuate wildly. The numbers above are the LOWEST I observed.
I will spend a little time looking into why this is happening. I certainly could be related to some add-on package that I have installed, but I don't every recall seeing BBEdit or SublimeText behave so poorly with all of the customizations I have thrown at them.
Update: added disk space for base app. Even with a 500GB SSD, Atom would make me think about its value vs space usage.
Update 2: the system specs. 2011 MacBook Pro 13-inch, 2.3GHz i5, 500GB SSD, 16GB RAM, OS X 10.11.2
Update 3: performed a clean reinstall of Atom, removed all third party packages, removed preference files, disabled Markdown preview. Atom is still using over 80% cpu and greater than 1GB RAM with one short markdown file open
