Thanks @rbirkner, this was very informative and useful. Given that the block rate is being slashed in half (from 600ms to 300ms) this would mean that the max_ingress_messages_per_block in relative terms is kind of doubled (not per block, but in terms of messages that can be written to a block per second).
Can I ask for some more info about the rationale for having it set to 1000 (i.e. why it’s not lower or higher)? I’m asking mostly out of curiosity
