Slow epub display


Is it possible to have epubs indexed but not displayed in the document viewer when selected? Their display in DT is extremely slow (maybe 20 seconds, half the time beachballing). It’s a real frustration when such a file in search results is clicked by accident.


Just curious, files on cloud (more specifically iCloud) or local hard disk? It’s seems to me that there’s a difference between the two.

It’s a local database on internal SSD.

How large is the file actually? I don’t experience any delays over here.

Could you please launch Apple’s Activity Monitor application (see Applications > Utilities), choose the frozen DEVONthink in the list of processes, select the menu item View > Sample Process and send the result to cgrunenberg - at - Thanks in advance!

I’ve sampled CPU usage on files of 3 different sizes. Sending them to you now. The non-scientifically-measured delay in displaying the files are:

  • 8mb epub : 3 seconds.
  • 16mb epub : around 10 seconds.
  • 76mb epub : more than 20 seconds.
