Really ? I feel the exact opposite. Eclipse performs much, much better than Android Studio. Just having AS open is enough to kill any and all performance on my laptop, not just AS itself but the whole machine crawls. I have no issues with having shitloads of other software running the only thing that has such a dramatic impact is Android Studio.

It's not even using that many CPU cycles according to Activity Monitor but it slows down everything regardless. It seems to always be doing some bullshit, indexing or whatever even if it's just open in the background.

I'm running this on the latest model MBPro which has a super fast SSD and 16GB RAM. I usually have at least one Eclipse instance running with a Glassfish server. Also, Postgresql, Safari with 100-150 tabs open, countless text editors I use for not taking, usuually I have some graphics editors open too (Affinity Designer and Pixelmator), Chrome with a few tabs and Postman, Wireshark, Mail, Calendar, etc.

All this while driving a 4k screen in simulated-2560x1440 'scaled' mode (so it's basically rendering at twice that and scaling it down to 4k). All that runs smooth as butter. The only thing that seems to be able to get this machine on it's knees is Android Studio, no matter what I do. The only thing that seems to improve things a little is AS's power save mode.
