> Playing around with the new temporal controller I notice that it loads all features from a layer and then (I'm guessing) filters them in memory to draw on the canvas. I noticed it because I disconnected my laptop to go work from the couch while we watched some TV and my data is in a a PostGIS database. My complex is absolutely filled with wifi APs so collisions are rampant and speed is horrible, but with the old Time Manager plugin it was doable because it added a filter that only loaded from the DB the features that were necessary instead of all of them. That method of Time Manager also made things doubly snappy over the gigabit wired link compared to 117Mbps on WiFi.<br>
<br>
That's only the case in very rare circumstances - usually the filter<br>
is indeed handed off to the underlying database in order to utilise<br>
whatever indices have been setup there. What temporal settings do you<br>
have on your layer?<br>

> Perhaps the temporal controller could use that idea to manage things better? Could it possibly help with tickets like 39856 and 39798? Also, I notice that the attributes table for temporal labels also has all features, even the ones that are not showing, and that is confusing.<br>
