<p class="MsoNormal"><span lang="EN-US">Hi,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I use a Python-Script to load all shapefiles in a directory tree one by one and export the sld-files.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">It works fine, but slows down incredible after ~100 files.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">So I tried the following barebone script with just the essentials (load shapefile, add it to the map canvas, remove it again and then clear the project) in a loop and I get the same behavior…<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">from datetime import datetime<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">for i in range(1, 1000):<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> vlayer=QgsVectorLayer ("aShapeFile.shp" ,"run " + str(i) + " at " + datetime.now().strftime('%H:%M:%S') ,"ogr")<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> QgsProject.instance().addMapLayer(vlayer)<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> QgsProject.instance().removeMapLayer(vlayer.id())<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> QgsProject.instance().clear()<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Same result, the Script slows down after every iteration in the loop AND QGIS-memory consumption goes up!<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Do I need to do some garbage cleaning / what am I doing wrong / is this a Memory leak?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Thanks everybody for any hints / help!<o:p></o:p></span></p>
