valerio.bozzolan added a comment to T108586: Herald rules causing delays to task edit saves - getting worse.
Yep @A_smart_kitten I agree with you that I wouldn't invest days of work in a partial solution that speeds up just 20 rules. I evaluated that speculation first because it was at first glance the easiest and safer.

@valerio.bozzolan Admittedly I'm out of my depth here, but I'm not sure if async Herald rules would necessarily have to be limited to non-content-affecting actions? I included this in the upstream task I filed:

Jdrewniak updated subscribers of T409354: Evaluate and improve perceived performance of loading ReadingLists Collections.
This would be a good candidate for using Codex PHP (cc: @Catrope ) and I think we should implement some kind of server-side rendering for this page for a general release. Performance gets more problematic the more cards are loaded on the page (could be an issue for mobile app users who have lots of saved items). When rendering this page via JS, the browser looses the ability to do any preloading or preconnection for image resources and doesn't prioritize them the way it would if the cards were server-rendered.

P.S. in phabricator.wikimedia.org - has it ever been necessary to manually disable Herald rules for de-activated ("disabled") users? Just to know whether to open another upstream feature request (yum).

SD0001 added a comment to T208578: SVG client side rendering for specific SVGs.
A new SVG sanitizer has been built (originally for T407783, hack attempts welcome!), which could be used for client-side rendering. This would avoid the security issues from users opening the image in a new tab, even without a CSP policy. Essentially, we could keep the transformation step but do SVG -> sanitized SVG instead of SVG -> PNG. While we're at it, multilingual SVGs can be handled with some postprocessing to avoid client-side language selection (process elements with systemLanguage attribute and check if it matches the lang= of the thumbnail - remove the attribute if it does, or remove the element if it doesn't).

- in core docker-compose.override.yml, add two new keys under function-orchestrator:
entrypoint: [] command: "npm start"
and add under its environment:
NODE_OPTIONS: --expose-gc
- in Orchestrator package.json, replace "start": with either "node --trace-gc server.js" or for more verbose GC logs"node --trace-gc --trace-gc-nvp server.js",
