Marshalling a json.RawMessage is not zero overhead. Instead, it compacts the raw message which starts to have an overhead at scale. https://github.com/golang/go/issues/33422 Since we have full control over the message constructed, we can simply write the byte slice into the network stream. This gives considerable performance boost. ``` goos: linux goarch: amd64 pkg: github.com/mattermost/mattermost/server/public/model cpu: Intel(R) Core(TM) i5-8265U CPU @ 1.60GHz │ old.txt │ new_2.txt │ │ sec/op │ sec/op vs base │ EncodeJSON-8 1640.5n ± 2% 289.6n ± 1% -82.35% (p=0.000 n=10) │ old.txt │ new_2.txt │ │ B/op │ B/op vs base │ EncodeJSON-8 528.0 ± 0% 503.0 ± 0% -4.73% (p=0.000 n=10) │ old.txt │ new_2.txt │ │ allocs/op │ allocs/op vs base │ EncodeJSON-8 5.000 ± 0% 4.000 ± 0% -20.00% (p=0.000 n=10) ``` P.S.
