<div dir="ltr">Hi Matthias, <div>in my tests that were made a few month ago, it was a lot faster on project load and a bit faster with parallel rendering for multi layer requests. Still I found it still slower than desktop rendering on the very same extent. I'm not aware of additional settings. </div><div>We did not have the opportunity to deploy a performance benchmark, maybe Yves can tell us if things have moved on this front?</div><div>Régis</div></div><div class="gmail_extra"><br><div class="gmail_quote">2017-10-04 14:15 GMT+02:00 Matthias Kuhn <span dir="ltr"><<a href="mailto:matthias@opengis.ch" target="_blank">matthias@opengis.ch</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi,<br>
<br>
I had some questions from people interested in performance.<br>
<br>
I advised them to set the following<br>
<br>
* QGIS_SERVER_PARALLEL_<wbr>RENDERING=True<br>
* Trust project flag<br>
<br>
Apparently parallelized rendering works (system stats) but it was<br>
reported to be slower than older versions.<br>
<br>
Is there something else that needs to be done? Is there more information<br>
I can ask for / give?<br>
<br>
Thanks a lot<br>
Matthias<br>
