Hi David,
everything you've detected happens since the transition to 3.x also on
windows 7 on PC with i7 4780 and 32GB ram.
any operation, even the simplest one, such as saving or calculating polygon
areas in a shapefile causes freeze of QGIS. Not to mention the node tool
where a forum should be open apart there is a ticket here but only 8 people
have participated ...
(http://osgeo-org.1560.x6.nabble.com/Node-Tool-proposing-improvements-td5387054.html).
Moreover:
- there is  no currently a native topological verification tool of
shapefiles (the new validator incorporated in editing is almost impossible
to run on shapefile with hundreds of polygon in ...)
It will take years, in my opinion, before the 3.x version can be used
productively.
Unfortunately, the gap between users and developers remains gigantic,
although most of the developers say that users have been asked .. sin until
2.18.x everything was wonderful.

I Hope that somebody from QGIS.org can see our perplexities and adjust as
far as possible this version which for now remains only a container of good
ideas

Regards
