So, I prepped this PR now:

https://github.com/systemd/systemd/pull/10780

It's not quite at the 1M yet you requested. I am not sure we should go
to the max right away, hence 512K, as something that is higher than
the 300K you saw, but still leaves some room upwards.

I hope this makes sense,

Lennart
