Description
This issue has been migrated from [#12463](https://github.com/matrix-org/synapse/issues/12463).
---
On matrix.org or we're seeing a *lot* of traffic going over our VPNs, most of which is Redis related. We should try and reduce this a bit.
Some things that would help, in order of effort:
- [x] https://github.com/matrix-org/synapse/issues/12462 ─ This would allow connecting directly rather than over the VPN.
- [x] https://github.com/matrix-org/synapse/issues/12460
- [ ] https://github.com/matrix-org/synapse/issues/12461

Research direction
Start by reading the linked issue #12461, since it is the only remaining unchecked item. Compare it with the completed work in #12462 and #12460, then identify how the change can reduce Redis traffic between workers. Done means the remaining traffic-reduction work is implemented and its effect can be verified against the reported VPN traffic problem.
