That's really interesting! I have an up-to-date atom install that i've been adding plugins to for about a year now (up to like 50 or so), and has been running for at least 12 hours (windows 10), and currently has 7 ~500 line files open.

Adding up all the processes' (7 of them) private memory gets me 194mb.

I installed the 64-bit version, you might be using 32-bit.

No it looks like i'm running 1.15.0 x64.

It might just be a difference of platforms.
