    Hi Giovanni,<br>
    <br>
    I have found the reason why QGIS Server 2.18 and probably 3 are
    slower than 2.14 in generating GeoJSON.<br>
    I'll fix it.<br>
    <br>
    Regards,<br>

          <div>Hi Giovanni,<br>
             GetFeatures  can output GML with a different format. <br>
            What is sure is that GeoJSON spec doesn't leave any choice,
            unless we go for a proprietary output format allowing
            another SRS. <br>
          </div>
          I'll keep that in mind when testing OGC compliancy for WFS. We
          are working on that currently to evaluate how much work is
          needed to reach a certification for WFS. <br>

            postgis datasource of<br>
            >> around ~25000 polygons) 2.18 is about 30 seconds

            > This issue is simply due to the transformation of the

            <br>
            ok thanks, but one doubt: I guess that this change (compared
            to 2.14)<br>
            was to make qgis server more compliant and this also means
            that we<br>
            need to accept that for such requests will be always slower
            than it<br>
            was before? sorry for the dumb question as I'm not much into
            the ogc<br>
            internals.<br>
