I see another known performance killer:
3rd Party Preference Panes:
Flash Player (installed 2019-11-22)
Java (installed 2017-07-21)
> Trusteer Endpoint Protection (installed 2018-09-18)
Trusteer has been trouble for a long time. I only see the Preference pane but it hints that others components may be present. See: https://www.ibm.com/support/trusteer/?lc=en_US
Your drive's write/read scores are low for a Fusion drive setup:
Performance:
System Load: 1.45 (1 min ago) 1.14 (5 min ago) 1.12 (15 min ago)
Nominal I/O speed: 0.89Â MB/s
File system: 54.90 seconds
> Write speed: 93Â MB/s
> Read speed: 81Â MB/s
Should be closer to 200MB/s if memory serves me (or not!). We have a geriatric 2011 iMac with a stock 3GBps 7200 rpm roto-drive that tests faster, up to 110MB/s.
Like others I would have you rerun EtreCheck after evicting all the dungware. I have seen cases here where drive scores increased once the poop was scooped. If they remain low, then you need to have the drive looked at by the pros.
