[Qgis-user] Lizmap for publishing QGIS maps on the web - new version 2.8.0

[kimaidou]

Hi Mirko

Do not forget Lizmap is webmapping, which is completely different from
desktop environnement.
If you ask 10 tiles per layer (depending on your screen size) for 20
layers, you will launch 200 request at a time.

You can improve perfs with many ways :
* Use the "group as layer" option to transform a group of qgis layers in
one signel layer in Lizmap
* Use the "single tile" option if you do not use Caching.
* Simplify your symbology and simplify complexe geometries for big scales
* Optimize your raster : use compression and pyramids !
* Use server and/or client cache (only if you do not use "Single tile")
* configure your server : Apache and fcgi. You must normally have several
apache threads and qgis server threads running
* etc.


Happy lizmaping !
