Call WriteMessage directly in websocketconn.Conn.Write.
...
In the client←server direction, this hits a fast path that avoids
allocating a messageWriter.
https://github.com/gorilla/websocket/blob/v1.5.0/conn.go#L760
Cuts the number of allocations in half in the client←server direction:
$ go test -bench=BenchmarkReadWrite -benchmem -benchtime=5s
BenchmarkReadWrite/c←s_150-4 597511 13358 ns/op 11.23 MB/s 33709 B/op 2 allocs/op

Stop storing version in ClientPollRequest
...
This continues to asserts the known version while decoding. The client
will only ever generate the latest version while encoding and if the
response needs to change, the impetus will be a new feature, set in the
deserialized request, which can be used as a distinguisher.

Validate client and proxy supplied strings
...
Malicious clients and proxies can provide potentially malicious strings
in the polls. This validates the NAT type and proxy type strings to
ensure that malformed strings are not displayed on a web page
or passed to any of our monitoring infrastructure.
If a client or proxy supplies an invalid NAT type, we return an error
message. If a proxy supplies an unknown proxy type, we set the proxy
type to unknown.
