This part of your report concerns me:
Performance:
System Load: 2.18 (1 min ago) 2.45 (5 min ago) 4.81 (15 min ago)
Nominal I/O usage: 0.02 MB/s
File system: 24.97 seconds
Write speed: 1397 MB/s
Read speed: 1224 MB/s
Those read and write speeds, for a modern SSD, seem sub-par. My 2019 MacBook Pro Intel laptop reports 3000 MB/s when I run Etrecheck on it. There could be a couple of things going on for you:
Depending on how you use Google Chrome, it might require a lot of your memory, and you have only 8 GB, which is marginal for a modern computer. When you run out of memory, your computer pages to disk, so the fact that your internal SSD is apparently performing poorly (slow) will slow everything down.
I suggest that you open Activity Monitor during times when your computer seems unresponsive or slow and see what is taking most of the cpu, memory, and energy. Take note of "swap used" -- is that a large number several GB or more?
As previously suggested, shut down or uninstall Chrome and see if performance improves. And the Cisco VPN should be either uninstalled (with Cisco's uninstaller) or shut down, as a test (you can always reinstall it), and certainly it should be updated if you need to use it going forward.
The slow disk read/write speeds is not normal. I get faster speeds with an external SSD connected via USB-C on my laptop. The internal SSD should be 3x faster than it apparently is. Try rebooting your Mac in safe mode; then boot normally and check performance. Also, you can boot into recovery mode and run Disk Utility First Aid to see if any errors are shown. Then reboot normally and without starting Chrome, try other software or browsers and compare results. If, after that, Etrecheck still shows slow disk read/write speeds, I would try DriveDx to assess drive hardware health. If none of this pans out, a visit to an Apple Authorized Service Provider might be in order, for better diagnostics on your hardware.
