I concur with Owl-53.

1) Uninstall McAfee as per the developers directions.

2) Startup in Safe Mode followed by a normal restart.

Start up your Mac in safe mode - Apple Support

3) Run a new EtreCheckPro report and post it.

Thanks den.thed. Here's my EtreCheck report. Any help will be much appreciated.

Not to take over the from very good work of my colleague @den.thed  + 1, but to work in collaboration with them 

disk0 - APPLE HDD ST2000DM001 2.00 TB (Mechanical - 7200 RPM) 

disk1 - APPLE SSD SM0128L 121.33 GB (Solid State - TRIM: Yes) 

This makes this a Fusion Drive setup 

Although the SSD portion of the Fusion Drive is of a good size

Nonetheless, even with the 7200 RPM Spinner / Mechanical Drive - this could slow down the Performance of the computer 

Coupled with a highly Customized Software configuration,   as evidenced by “  System modifications - There are a large number of system modifications running in the background.” 

Looking further at the report.

There appears to software has been migrated over several years dating back to in some cases to com.mcafee.virusscan.fmpd.plist (McAfee, Inc. - installed 2019-06-11)  and [Not Loaded] com.mcafee.ssm.ScanManager.plist (Not signed - installed 2014-10-07)

This could spell trouble 

No problem, two sets of eyes are always better than one.

I noticed the slower Write speed as well.

I was going to wait until we had an updated EtreCheckPro report, to see if the OP needed to run DriveDX on the iMac's drives.

Good catch 👍, read / write speed

Something to explore for sure
