A part of the research is about the time needed to process simple tools (for exemple: buffer, clip, union, .). ArcGIS has the possibility to watch the log where you can see how long the program took to process. I was wondering whether QGIS has the same function. I was also wondering whether anyone of the QGIS community already did comparable research, or has read anything that could help me.

However, there may be a quite negative impact on performance, if you include such functions in your symbology impressions. So use them with care, only if you really need them!

The issue has been already reported in http://hub.qgis.org/issues/11968 In the meanwhile a manual filter could be set within the WFS add layer dialog. giovanni 2015-03-26 16:07 GMT+01:00 G.
