<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><p dir="ltr">As I reported in a previous post, I was unable to conclude a difference operation on a vector because the tool was running in exponential time.<br>


 <br>
Debugging pointed me to the problem: QgsVectoFileWriter was logging tons of empty geometres with an incompatible type which will be discarded. <br>
After commenting the line of logging the process completed in linear time. </p>
<p dir="ltr">Shouldn't we offer the opportunity to turn QgsLogger off? This would let the user/developer to switch it off whenever he already knows what's happening. <br>
Is it already there and I missed it? </p>
