>Seeing what kind of requests you made (zoom level and image size) is going to be interesting.<br>
<br>
Image 1000 x 600 - 1500 x 900, Zoom level 1:800 - 1:5'000. Zoom level has been selected because most of the cadasdral layers are visible on that scale.<br>
And yes, image encoding is a very important factor in this benchmark. However, I think it is a realistic scenario and image encoding as well as palette generation is indeed a very imortant thing for a WMS server.<br>
<br>
>however that really turns the benchmark into a png encoding contest<br>
<br>
In UMN as well as QGIS server, the palette generation for png8 is implemented as part of the server code (it does not come from a 3rd party lib). So I think comparing that in a benchmark makes sense. If a test would be driven by rendering speed, you could also
say that the test measures the performance of the underlying graphic lib.<br>
<br>
In any case, I agree that benchmark results are very specific and a different test may show a totally different picture.<br>
<br>
Regards,<br>
Marco<br>
