<div dir="ltr">Hello all<div><br></div><div>I have the situation that I want to cache an existing WMTS to my projects infrastructure to be more secure with 24/7 availability.</div><div><br></div><div>I try to cache 4 layers provided by swisstopo, the federal swiss geo data agency. This WMTS's are really fast and usually having no issues with catching the tiles.</div><div><br></div><div>I do setup my mapproxy to have this 4 layers definded in epsg:2056 and I also defined the correct grid sucessfully. Maps are cached on request and it works as expected.</div><div><br></div><div>All is running in a Docker-Container</div><div><br></div><div>Internet-connection supports up to 1gbit/s and shouldn't be a bottleneck.</div><div><br></div><div>But now If I try to preseed this 4 layers I can't get real performance out. I defined BBOXES in epsg:2056 to limit the area. I do not reproject anything. I simply store loaded tiles. In my understanding there shouldn't be a bottleneck somewhere. But there is. I tried the mapproxy-seed command with many different settings. Also with -c from 1-25. But there is no difference. The different spawned processes are using around 1.5% of CPU and net throughput is somewhere around 300kb/s if I use 25 concurrent tasks. It stays at around 50kb/s when I use one concurrent task.</div><div><br></div><div>Machine is a 8 core with 32gb of ram (not running into limits) and a usually fast SSD.</div><div><br></div><div>I write here because I can't come to a conclusion what might be wrong. Maybe it's something simple I miss here?</div><div><br></div><div>I Attached the 2 config files I use. </div><div><br></div><div>Cheers</div><div>Clemens</div><div><br></div><div><br></div></div>
