Problem spinning Imac late 2012 performance POOR

I get to see the spinning wheel with almost every action on my mac. Last week I cleaned out my entire mac and put everything back on it but the spinning wheel remains. I have now done the Etrecheck program with "Beachballing" and now I see that the performance is POOR. This is the report but can anyone help what the problem is now?


iMac, OS X 10.11

This is a about as big a red flag as you can get:


Performance:

System Load: 1.43 (1 min ago) 1.89 (5 min ago) 2.16 (15 min ago)

Nominal I/O speed: 0.37 MB/s

File system: 24.12 seconds

Write speed: 26 MB/s

Read speed: 69 MB/s


Even an entry-level iMac 21.5" with a miserable 3GB/sec 5400 RPM roto-drive will post drive scores of 50-70MB/sec.


With a 6GB/sec SSD your read/write speeds should be in the range of 500GB/sec. That points to massive issues with your Kingston SSD. Generally Crucial and OWC SSDs perform best in Macs.
