Why is QGIS so slow to get results?
This is frustrating because any modification of the project, however slight, requires a lengthy wait before the results can be assessed, and sometimes the application simply crashes without completing whatever I asked. Is this unusual? I have Shapefiles of the same data.
Why does QGIS take so long to delete attributes?
To its credit QGIS did complete the task, unlike LibreOffice which simply crashed, however it took 36 hours* to do so! During the process I realized that part of the performance problem stems from the approach QGIS used to delete the specified attributes i.e; removing them column-by-column, then rewriting and reloading the database each time.

Why does QGIS get blocked in the UI thread?
Clearly QGIS is doing file operations in the UI thread, or at least it’s getting blocked by them, which is.. not ideal. I don’t know enough C++ to try to fix it, but let me know if I can help in some other way. The workaround from #33164 might help: “hide from Browser” for certain mount points (“drive letter” in Windows).
Why does QGIS freeze when disabling a VPN?
