High memory usage, macbook pro retina feeling sluggish
Your information is very good for RAM and CPU, but I don't see anything amiss and things look quite balanced. Yes, there is one program that's busy and not responding, so you could kill that to rule it out as something that's slowing down Photoshop.

My hunch is you will need to examine storage to find the slow down. 

My reasoning is Photoshop does a good job of pre-allocating disk space for swap of it's own (so it doesn't even swap to the OS swap) as well as pre-allocating all the RAM it thinks it will need. Even without seeing the normal RAM and CPU charts you posted, it's unlikely your Mac is paging virtual memory to disk based on the stats you posted from a snapshot in time.



Open terminal app from /Applications/Utilities and run two commands to list the attached drives (so you know which is disk0, disk1 etc...) and another to monitor the actual input and output for the drive.

df | grep disk
iostat 30


The second command will run continuously until you press control+c or close the terminal app or window.

My guess is you will see that there is continuous load on one or more disks and quitting the programs that are causing the disk to be busy will make Photoshop more snappy. You've already ruled out high CPU load and memory contention (the pressure would be yellow or red if that were to slow down Photoshop) so the next likely candidate is that the system is waiting for the storage.

The other suggestions to try killing other applications are good ones, but you will be more successful if you can measure the exact slow item and then change things and re-measure later.

Here is a sample of what you might see on an idle system:

Mac:~ me$ iostat 30

Here is what first a minute of activity on the internal SSD then idle, then a minute of activity on the Time Machine drive and idle, and finally Time Machine running with both drives having equivalent activity (read from one = write to another):
