Hi Matthias, 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. We did not have the opportunity to deploy a performance benchmark, maybe Yves can tell us if things have moved on this front? Régis
