Bug report #15310

Selecting many features in the attribute table is very slow

Description

Load eg. ne_10m_populated_places.shp

Open the attribute table

Click the rightmost "external" column of the table to select the first row, then scroll all the way down, hold Shift and click the last one.

On my i5 system this takes about 15 seconds until the selection appears and QGIS gets responsive again. It is even much worse if editing is enabled.

"Select all" via Ctrl-A or the icon is instant.
