ObjectDock Cause of PC Slowness?

ObjectDock not supported on Windows 10? (see the link) Well, I guess that's right (listed for 8/7), but I'm a long time user, until yesterday. I've begun having lagging problems, particularly with YouTube videos sound, and with the cursor movement. So, I started hunting for causes/solutions.

I have noticed sometimes that ObjectDock fails to load after restarting PC, and instead then loads from a saved copy. Although a little sluggish at times, otherwise OD has seemed to work fine. But, when I killed OD from Task Manager, I found a definitely improved response from my PC, and lack of the YT audio stuttering. So, now I've set OD to not start on PC startup. I can live without it, but I'd rather still have it to use, as I've become to rely on it. I can start it when needed from a shortcut icon, then kill it. But is there another way?

I'm also running Start11, Fences, Groupy and CursorFx.

Windows is installed on a NVMe board, and I have other SSD and HD disks.

As I write this, Memory usage is 52%, CPU usage is 29- 48% without OD running. After starting OD, memory usage is still 52%, and CPU usage is about the same. OD is quite responsive. I've noted in the past that it becomes sluggish, particularly after hours of running.

Any suggestions?

Thanks.
