So with 3.24.1 going live, CIG also enabled RMQ replacing NMQ -
RMQ, Replication Message Queue, is the newest iteration of NMQ, Network Message Queue. It allows us to us to 'listen' to far more information requested by players, such as opening doors, equipping items, etc..., to better manage interaction delays. Now that this new system is ready, we’d like to have the community test it to continue improving it. Right now, some servers are running on NMQ, and others on RMQ, to compare the data. When the time is right, all servers will switch to RMQ.
Basically better performance, Less bugs from various actions
