Thanks all. Jesper: I will try those things and may look to force a GC when I do my redcuing of the map. Your explanation was very useful! The application is processing a fast stream from RabbitMQ so yeah there is a lot of throughput onto this map.
Egon: Can you explain what to and why this would help? 刘桂祥: I do currently have it as map[string]*struct, how will changing it (in what I can see two places) make a difference. The key to a byte and then a value in the map.
