<p>Hi Nyall,</p>
<p>You are right. GRASS and SAGA take the longest time in initialization. Perhaps we should disable those by default. I think both are for advanced users. These users should know how to enable the SAGA and GRASS providers, should they need them.</p>
<p>Here is the screenshot from my QGIS on Linux (without SAGA) (I'll send another one for Windows later):</p>

<p>Seems like DataPlotly also takes substantial time to load.</p>
<p>Greetings,</p>
<p>Andreas</p>

<br />Yes, I think there's lots we could do. But I'd love to see a<br />screenshot of the new startup time profiler for one of your affected<br />slow-to-start machines.<br /><br />Typically the culprit is the GRASS and SAGA providers, where they load<br />algorithms from 100s of text files. File access like this on Windows<br />is very slow, so I think the easiest thing to try first would be if we<br />concatenate all the definitions into a single master text file...<br /><br />Nyall<br /><br />
