I've got an iMac that is performing quite poorly. The specs:
- OS X El Capitan
- 4.0 GHz quad-core (i7)
- 16 GB RAM
I've tried everything possible to figure out what's going on, to no avail. Typically the machine has a few Adobe apps running (Photoshop, Illustrator), and Google Chrome with a bunch of tabs. Performance becomes horribly bad, rendering Photoshop almost unusable. The odd thing I noticed is that swap starts going up (to 10 GB in some cases) even though the physical RAM is only half exhausted.
Unfortunately I captured this after Photoshop was closed (which seems to help some). But while Photoshop is open, "Mem" is up to about 9-10 GB, and "Swp" can go as high as 10-12 GB.
The Activity Monitor shows a relatively low memory pressure (still in the green), so I'm not sure what the issue is. This is a pretty high-powered machine that shouldn't be exhibiting this behavior. I'm not sure if Adobe is the problem, or there's something wrong with this computer. How do I start to troubleshoot this?
Just to elaborate on the poor performance: simple things take way too long, such as nudging a layer over, or zooming in (as in, over 8 seconds for a simple operation!).
