High CPU usage in idle
While leaving On1 alone on the browse pane the programm creates about 50% CPU usage on my Ryzen7 1800x and the disk utilisation ist jumping between 20 and 70% (7200 rpm Barracuda Pro). This behaviour does not change even after a night of not touching anything.
How can I reduce the resource utilization of this program?
-
In Preferences > System there are a couple of sliders for controlling the program's system utilization you can adjust.
Are you creating any Catalogs? The cataloging process has to render every image in the catalog so it does push up the system's utilization as each image is read from the drive, rendered, and the rendered preview saved to the program's PerfectBrowseCache. Once the cataloging process has finished the system utilization will return to normal levels.
You can read more about the cataloging process at https://on1help.zendesk.com/hc/en-us/articles/360035750991-Catalogs-and-Caches-ON1-Photo-RAW-2020.
Also, the cataloging process can hang if it runs into files it recognizes but cannot work with. There is a current discussion here on the forums about this at https://on1help.zendesk.com/hc/en-us/community/posts/360048188751.

I am creating a catalog of my about 60k images. It seems I have been stuck with the unprocessable file bug. I have removed all files that have been named in the log and restarted the program. After moving the PerfectBrowseCache to a SSD i'l leave it running for a night more and check the log file again.
It is a little disappointing the the program gives no indication of a running background process. A line in the footer to show what is going on would be nice.

60K images is quite a bit. I would expect it to take at least a day to complete. I have about 14K and it takes about half a day to finish. You've got 4 times as many images so it could be 2 days.
There are supposed to be progress indicators on the folders in the catalog that it is working on. If you don't have the entire file structure visible though it can be difficult to find them.

BTW, the PerfectBrowseCache seems to be limited to 10G. Is that correct?

No, the PBC will take as much space as needed to store the previews for all your catalogs and the folders you browse through.
I assume you are referring to the BrowseCache setting in the Preferences > System panel. That controls a memory cache, not the amount of disk space used.

According to the article linked in the post above, 50K photos will take 53 to 85 gig, so 60k photos will take 65gig or more at std settings.

The program crashed during the night , probably because the "ON1 Photo RAW 2020 Cache" filled up the disk. The directory was cleared during a restart of the program. It seems one needs unlimited space during the catalog process of a larger number of files.
Now that the Cache directory is empty again the catalog process seems to continue.

Unless you changed the size of the previews generated for the catalog you're probably going to see the same thing happen. I recommend adding an SSD for the program's Scratch space and its PerfectBrowseCache where the catalog previews are stored. You don't want to fill your internal drive to capacity or even near capacity and an SSD will solve that problem. And additional advantage, and the reason I recommend this even without the problems you are experiencing, is that you'll see a huge improvement in the program's performance. The cataloging should go faster as well as not all the I/O involved in reading the image file, rendering it, and saving the preview (along with all the scratch space I/O that takes place) will be taking place all on the same drive.
You can see the controls for moving them in the screen shot above.

I used a free 250G SSD for that. It seems that this is not enough. As soon as I get my Hands on a bigger SSD I'll try again.
According to the table 250G should be plenty, even for my 4k monitor.

It seems there is an answer for 14k images. I know the answer to 160k+ images.
