<br>
We have massive boundary relation<br>
( <a href="https://www.openstreetmap.org/relation/49715" rel="noreferrer" target="_blank">https://www.openstreetmap.org/<wbr>relation/49715</a> for example) and AFAIK<br>
everything works fine.<br>
<br>
Is this performance concern is confirmed by anything? Messages from<br>
people handling OSM servers, profiling, anything like that?<br>
