I haven't heard back on the GitHub issue for a few days now. Not sure we'll be able to get the process tuned to get more jobs done any time soon.
Meanwhile, it seems the speed has improved a bit without any changes, no idea why. It's now doing a bit over 70000 jobs per day. The queue currently is at 370000, which means somewhere this weekend it should be caught up.

Then we can carefully try to re-enable some features that we disabled, like the Bluesky bridge, and contacts discovery etc.

I've opened a second issue for help on enabling the mail connector: github.com/friendica/friendica…
