I noted that Devonthink (V 3.9) kept one core of my 10-core MBP (M1 Max) 100% busy even though nothing of significance was going on. An idling DT typically only uses a few % of one core. Turns out, the document selected in the DT window was a web location pointing to a GitHub page, and the page is rendered (e.g. in Standard or Widescreen view). I found that puzzling, as GitHub seems to serve essentially static html. Displaying non-GitHub webpages, even with dynamic content does not grab any significant CPU share. Is the GitHub page doing something in the background? If I open the same page in Safari, CPU usage stays low. So it’s a combo of GitHub and DT webview that hogs reliably 100% of a core. I tried several different GitHub projects and this happens in all cases.
Development will have to look at this and see if there’s anything that can be done on our side.
I have alerted Development with a process sample while browsing GitHub in DEVONthink. They’ll assess the specifics better than I can
