Hi dev's, I was notified some performance matters when dealing with selections in attribute tables, by some users swithcing from arcgis to QGIS. Indexes of datasource seem to be ignored for SQL selection and search. This leads to very slow selections when dealing with large datasets. Anyone confirms? Is it really related to indexes or another bottleneck? Is there any possible improvement ? Are providers working on selections or is that all dealing with cache?
