Re: [Qgis-user] questions about the FOSSGIS 2013 benchmark comparisons between QGIS Server and UMN Mapserver
Thanks Marco. Caching, caching and caching :) Next days I'm going to setup a QGIS server from master to test the improvements. I will also test its behaviour behind a MapProxy instance with tiling and a complex labeled layer, to see the outputs with meta tiling and tile buffering. I'm gonna stress it! giovanni 2013/6/22 Marco Hugentobler marco.hugentob...@sourcepole.ch It is important that you test QGIS master not QGIS 1.8. QGIS 1.8 was definitely slower than UMN, but in master there are performance improvements in the server part. Marco knows the details. There have been a lot of performance improvements in QGIS core (e.g. the new raster system, svg cache, more performant coordinate reprojection, CRS and Coordinate transform cache, project file cache, ...). Nore that the benchmark especially measures the scalability of the WMS server (many concurrent requests). For scalability, it is important that as much is CPU-based and data comes from RAM rather than from disk. While a desktop user e.g. does not notice a request to the sqlite DB to lookup a CRS definition, this small disk access had a big impact on scalability. Similarly for SVG files, project files, coordinate transformations. All these things are cached now on first usage.

In the past performances didn't appear better then Mapserver. Marco (and the ohters from Sourcepole), could you share the configurations adopted for the benchmark?

Re: [Qgis-user] QGIS Master dependency problem.
Hello, I had the same problem with QGIS on Ubuntu 12.04 (at work, but not at home :-O ). Apparently, there is a typo in this file : /usr/share/qgis/python/plugins/GdalTools/tools/doPolygonize.py, at line 108 if self.fieldCheck.isChecked() and self.fieldEdit.text()): the opening parenthesis lacks. Il should be : if *(*self.fieldCheck.isChecked() and self.fieldEdit.text()): I've corrected this typo, then uptaded problematic packages (especially python-qgis-common). There was no problem any more with updates. Hope this helps!

[Qgis-user] How to display point symbols on top of labels
Hi all I'm using new labelling (from layer menu, not from layer properties) to show street names. On the same map, I have defined symbols on a point layer. Is it possible to display point symbols on top of street names ? In my case, street names are always drawn on top of all other map objects.

[Qgis-user] Binary hillshad raster for sunpower plant
Hello to everybody, I have to prepair simulations for a sunpower plant in project, considering the areas in shadow in the plant in certain sample days of the year in the whole day. The use of the plugin Hillshade is very easy to understand, but I cannot understand how to obtain a binary raster with value 1 for pixels in shade (colored in black) and 0 for the others (to see them transparent). I did it few years ago with ArcGIS the same task and it was really simple to achieve the desired result, while the same result with QGIS seems to me not so easy to do... Can anybody tell me how to do it? Thank you in advance for your help, Giuseppe Anardu ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
