I'm doing a lot (really a lot) of feature requests on a vector layer. These requests are capsuled in iterations and functions, so no way of reducing the total number of requests.
Although I consider the #1 tip concerning
QgsVectorLayer.getFeatures() - use a specific request whenever possible (Why use QgsFeatureRequest() when iterating?) - I end up with low performance and
cProfile tells me the bottleneck is still the feature request.
layer.getFeature(fid) instead of
request = QgsFeatureRequest().setFilterFid(fid) feature = next(layer.getFeatures(request))
doesn't make any difference.
How do I speed up my feature requests, when I know each feature is called lots of times?
