<p>Or maybe you could use something like MapProxy - which allows to fetch a bigger chunk of the data in a single request and chops it up into the tiles and caches them. Then the tiles wouldn't be served by QGIS server directly, but from the MapRroxy.</p>
<p>MapProxy has a concept of "MetaTiles" to help solve this label issue - see <a href="http://mapproxy.org/docs/nightly/labeling.html">http://mapproxy.org/docs/nightly/labeling.html</a></p>
<p>I am not really experienced with it - my guess is that the "MetaTiles" only partially solves the issue, but doesn't fully fix it.</p>

<div class="gmail_extra">Hello, <br /><br /></div>
<div class="gmail_extra">from QGIS Server point of view, a tile is just a small map, it doesn't have any information about the fact that the tile will be patched to build a bigger map.<br /><br /></div>
<div class="gmail_extra">You should disable annotations from the project configuration if you are planning to serve the map as tiles.<br /><br /></div>
<div class="gmail_extra">If you want to keep that configurable, you might want to move annotations to a particular layer and selectively show/hide that layer depending on the requested image size, a simple Server plugin could be helpful in that case.<br /><br /></div>
