Are your projects on their own drive?

One of the biggies is that Defender real time scanning is disabled entirely. Defender scans during idle periods. If I have any doubt at all about a downloaded file, I scan it manually.

SK, how do you get Windows to allow that? Please share with screenshots if you can. 

My Win 11 looks like this, is asynchronous what real time scanning is?

Here's what my Settings page for it looks like:

As you can see, it says that it can only be turned off "for a short time." It also says that it's managed by an administrator.

It's not true that it can only be turned off for a short time before coming back on, but it is true that it's what will happen if you try to control it from that Settings panel. You have to do it from Group Policy Editor, and you also have to turn off Tamper Protection. If you don't turn off Tamper Protection, Windows will keep turning real-time protection back on.

Once you've done that:

1. Open Local Group Policy Editor (type gpedit.msc in the search box)
2. Computer Configuration > Administrative Templates > Windows Components > Microsoft Defender Antivirus > Real-time Protection
3. Enable Turn off real-time protection
4. Restart the computer

As you can see, it uses similar logic to certain locations in Sonar where you disable/bypass FX. You don't "disable" it, you enable turning it off.

Note that this recipe requires you to be running Windows 10 Professional. Years ago I figured out how to both enable Group Policy Editor and use it to turn off real-time protection on Windows 10 Home, but it's harder to make that one stick. Microsoft kept turning it back on when system updates were installed. So I finally caved and bought a Pro license, which can be had for about $10 if one searches Google Shopping.

Defender will still do its downtime scans, it just won't scan every read and write.

No. Drive D is all samples. Drive C is everything else - programs, projects, etc.

It runs quite well. I can have a lot of Sonar tracks & plug-ins before anything starts to drag.

You may find it better to keep your projects on a separate drive, even an external USB 3 NVME drive. The OS drive can be pretty busy with loading stuff, managing the Swap file, if you have not disabled hibernate or sleep then the hiber-file as well, plus streaming your audio. Just a thought for your consideration.

Brilliant work Erik! Thanks

Thanks, that's probably the next step once I outgrow my current config. For now everything is running well as is.

Going back to the OP .... Sonar freezes only about once per month, and triggers the PC fan to kick on until I kill the session. I thought that posting this condition might be useful to the Bakers, or other users if they encounter it.
