Description

I'm using QGis 1.7.3 (the same happens on 1.7.1).

With a polygon layer, and the new symbology with levels, QGis gets very slow and only uses one thread (it seems so), wich is strange nowadays with multicore processors.

sorry I didn't see that #3388 was already closed. Anyway you will need to provide sample data and further information to allow investigate if/where there is an issue.

Sorry, there's no issue.
Horizontal placement, in "Layer labeling settings", was inadvertently selected.
Sorry.

Sorry.

so the issue is in labelling?

Going to Labeling -> Advanced -> Placement, there are various options.
"Horizontal" specifically states "slow".
So this is not a bug, maybe a feature request.

work is being done to make labelling faster, especially with polygons.
