Hi, What is your cpu, gpu, memory amount. Do you have a hard drive spinning on another task like antivirus, Windows indexing... update windows and drivers. If you look at the task manager, try to see if one core in 100% busy. You may have a rogue task is overtaking the computer even if total cpu is low.
Could this be the geopackage fault? Somebody had a problem this week with increasingly slow geopackage performance...
