We have the same model iMac with the same hard drive specs and it feels slow due to the old-style drive and a slow interface. However, on the same test our read/write scores are almost twice yours. Once you back up the computer, evict the useless anti-virus and cleaning apps, and restart, run EtreCheck to see if the write/read scores in this section have improved:

Performance:

System Load: 1.41 (1 min ago) 1.45 (5 min ago) 1.34 (15 min ago)

Nominal I/O speed: 1.36 MB/s

File system: 25.49 seconds

Write speed: 60 MB/s

Read speed: 56 MB/s

Our 2011 iMac with the same drive is posting scores of 90-115MB/s.

Google Chrome is hogging over 30 percent of your already upgraded RAM. If you must use it, quit it when finished. Chrome will grab a bunch of resources if you leave it open in the background.

There is emerging evidence that outdated versions of DivX can slow a Mac. Your version dates to 2012. If yo use it, update it; in not, dump it.

It look like Photos is trying to upload a lot of stuff to iCloud and is jammed.

Network:

Interface usbmodemfd11: USB Modem

Interface en0: Ethernet

Interface en1: AirPort

iCloud Quota: 1.42 TB available

iCloud Status: 28 pending files

I'm not sure how to deal with that as I do not use Photos. Maybe someone else can help there.

real-time virus scanners slow most macs down to a halt, and you even have 2 installed both Avast, and Sophos, think that would cause problems even for newer macs
