Beachball spinning at startup

[gerlo]

The latest photo mechanic causes a huge time lag on my 2019 27' iMac (40 gb memory).
Starting the program with an empty contact sheet takes 27 seconds.
This happens every time I start the program. Before, it took seconds to reinstate 3 or 4 previous contact sheets.
I reinstalled the program from scratch, but that didn't help. It happens already a few weeks.
Any ideas on this?

When you reinstalled the program did you make sure to remove all files that the software creates or did you only delete the application from the Applications folder?

What are the settings in the caching section of your Preferences window?

I deleted everything connected to camerabits and photo mechanic. I just reinstalled version 6645. It takes only around 15 seconds to start up.
I set the cache to the maximum. See screen print.

An extremely large cache size can negatively impact Photo Mechanic's performance, especially start up time. Yours is set to 4TB, probably larger than the drive that stores it. Set your disk cache size to 1024, and the reserve at least size to 256, and set the memory cache size to 10%

that is already better. Still something wrong. Might be something on my computer?

Empty cache on quit if you want the start up time to decrease significantly.  Keeping the disk cache around only helps if you view the same set of images day after day.  For most users, emptying cache on quit is best.
