I have a number of standard projects set up for QGIS users. Some of them take more than 5 minutes to load. Things recently got much worse suddenly - and I want to track down why.
Are there any methods to check what stages of loading a project are slowing things down or/and how long QGIS is taking over each stage of loading a project?
In my particular case the issue may be related to internal network overload, and seems to be related to upgrades (at the same time) from Windows 7 to Windows 10 and QGIS 2.18 to QGIS 3.4. However, I think answers will be more useful for others/Stackexchange if they consider the wider question.
