In systems with a low number of connections, these connections may all exist on the same TMM. This causes uneven CPU usage and prematurely limits maximum message throughput.
-- Uneven CPU usage. -- The system will likely not reach the expected throughput.
-- Systems with a low number of connections. -- Connections are not evenly distributed between TMMs. -- This issue is exacerbated when the maximum message throughput is set to a lower value.
None.
With this change, the system can be configured to create new outgoing connections on a different TMM than the TMM that is processing the traffic. This enables better CPU distribution and higher throughput.
