daniel added a comment to T369898: Reduce the number of resource_change and resource_purge events emitted due to template changes.
Looking at metrics from LinksUpdate, it seems that we could reduce the number of purges a lot, if we wait until after we re-parse to decide whetehr we need to purge or not.

Whoop_whoop_pull_up added a comment to T352227: Work around cache partitioning in iframe sandboxing.
In the specific case of the Graph extension, I think the impact on servers is not very significant (it's mainly ResourceLoader load.php requests, which are cached in Varnish and scale well) but the bandwidth increase is quite large, about 0.3 MB per graph shown on the screen (that's comparable to the total payload size of visiting a Wikipage page with no images on it, so could be a 100% bandwidth increase per graph).
