Hello,
30s freeze is something which seems rather unpleasant for the user.
I am not experiencing such freeze. With a project with ~100 layers, with
10 having more than 10k features, I have something around 2 to 3 seconds.
I beleive this is reasonable.
Could we imagine to do the indexing in background ?
Indexing is started when an editing map tools (or I believe any snapping
operation) is enabled.
Since it is required on mouse events, it needs to freeze the app in the
mean time.
And maybe indexing only what is currently in the user's extent, if this
is not what is currently done ?
Would be an idea, although I am not sure this is really required. Nobody
complained very much yet about this.
Martin would have to answer for saying if it's feasible or not.
Indexing a whole layer for editing seems a no-go. We should maybe have a
way to get the user to use the indexing tools only when zoomed in ?

Dear Nicolas,
The indexing is used for snapping in the application.
It takes a few sec when enable the first tool, but snapping is much
faster later on.
Best wishes,
Denis

Hello,
I'm using QGIS 2.10.1 and 2.8.3 with PostGreSQL 9.3 and PostGIS 2.5 under
Linux openSUSE 13.2 64bits.
A strange things appear since i've move from PostGreSQL 9.1 -> 9.3
Each time I open a layer for editing, when I selected any tools (node
tools
or creation entity tools), QGIS freeze about 30 sec and display 'indexing
data' progress bar. (memory of my computer grow up in same time)
After that, I could editing my data, close it and reopen editing session
whithout any problem or any crash.
But if I close my project and reopen it, again indexing data when I
want to
edit a layer.
I've seen that new thing under a small layer (90 entities) and bigger one
(about 250 000 objects), same things for Polygon or Point geometry.
I've a primary key constraint and a spatial index.
Have you already see that somewhere else ? I can't find why as it never
happens before.
Best regards,
Nicolas
