Is this done?
What parameters are set in Status apps?
Since what release?

Looking at the code, the rate limit is set for lightpush and peer-exchange.
Both of these with 1 request per second.

This was added 4 months ago in the following PRs (cc: @vpavlin)
status-im/status-go#5504
status-im/status-go#5504

These are available since release v2.30

It's missing for filter. Should be relatively straightfwd to implement so we get it on the next release.

cc @chaitanyaprem should we review the 1 req per sec to a higher limit?

I have already increased for publishing and filter side. Will have to increase for lightpush service-node side as well until we bring in rln.

Including it as part of status-im/status-go#5964

Re-opening pending testing.
