Thousands of messages per minute in system console. Mac is slow by doing lots of things.

Long ago I was doing some sketchy stuff with my Mac and damaged the system. I can't recall what I was doing but almost sure it involved disabling some integrity checks or something. Now the Mac is slow by doing thousands of task every minute as per System Console. I'm almost sure the damage is reversible but I need someone who can have a look at it. I've downloaded EtreCheck and performing scans now. But they are not going too fast...

What can I do in the meantime? Should I post my console log?

iMac 21.5″, macOS 10.15

Don't use Console. Quit the app. It's normal for a Mac to perform thousands of tasks per minute, and merely having the Console app open will cause your Mac's performance to suffer.
Post the EtreCheck report.

It is possible that Windows is willing to boot from a failing drive that macOS isn't willing to boot from and risk losing your data.

If the bad blocks were on the Win8 partition, it wouldn't run well either.

Forget whatever tool you may have used — the EtreCheck report conclusively reveals that Mac's hard disk drive is operating in an advanced state of failure. If you want to keep that Mac in service it can be replaced.

Should you decide to do that, I strongly recommend replacing it with a solid state drive from a reputable manufacturer such as OWC / MacSales. Their Mercury Extreme Pro 6G models are the only SSDs I have ever used and can personally recommend. The oldest one is well over a decade old and still works as well as it did when it was new.

The presence of the aforementioned non-Apple "cleaning" tool obviates everything though. Whether it caused or merely contributed to its early demise cannot be determined; the bottom line is that such things wreck perfectly good Macs. Uninstalling it won't help. The damage is done.
