ftool Vector Grid Slow in master #16311

Author Name: Angus Carr (Angus Carr) Original Redmine Issue: 7322 Affected QGIS version: master Redmine category:processing/qgis


Comparing master to 1.8, using the plugin that came with QGIS (0.62). Vector Grid output as polygons is fine at 6 or 8 polygons to cover the space, but when the resolution is increased to 100x as many, it slows down and stalls. In 1.8, it runs in seconds, although there is a pause. In master, it runs for minutes, (10?).

The attributes are NULL, too, as a side effect of the Vector API switcheroo.

If is a regression then this should be tagged as blocker.
