<div dir="ltr">Your I-7 likely has 4 or more logical processors. The only way to go over 100/N where N is the number of processors is to have 2 or more things (continuously) running simultaneously (like loading a complex web page in a browser). Scripts are going to run as a single stream which will bounce around between processors, giving an average user of 100/N% If you have 4 processors, 25% would be from the script and another 5% handling disk I/O, network, and other Windows tasks. That would result in the 30% you see. Parallelizing script execution is complex and I doubt that it is currently done in QGIS.</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Apr 15, 2021 at 1:03 PM Wolfgang Meinolf <<a href="mailto:wmeinolf@bbv-deutschland.de">wmeinolf@bbv-deutschland.de</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p class="MsoNormal"><span lang="EN-US">Dear Community,<u></u><u></u></span></p>
<p class="MsoNormal"><span lang="EN-US">I use Qgis quite a while under win10 and ubuntu (via Oracle VM Box). My FTTH scripts include GRASS i.e. v.net.steiner algorithm, which are quite CPU and memory intensive. However I never observed more than 30% CPU and
never more than appx 4GB mem usage. My Hardware is Intel I7, 32GB Ram and 1000TB SSD. At same time I don’t observe any other activities i.e. on network. I installed OsGEO4W the 64bit Version. I’. currently on 3.18.1<u></u><u></u></span></p>

<p class="MsoNormal"><span lang="EN-US">I would appreciate any hint, how I can increase the CPU and MEM Load, to accelerate my scripts, which run usually quite a while. What do I wrong?<u></u><u></u></span></p>
