Сохраните профиль потребления памяти.

Запустим 2 сервиса и дадим им чуток поработать.

server

mkdir -p ./profiles/server
mkdir -p ./profiles/client
curl http://localhost:8080/debug/pprof/allocs > ./profiles/server/allocs.base.pprof
# go tool pprof -http=":9090" -seconds=30 http://localhost:8080/debug/pprof/allocs
go tool pprof -http=":9090" -seconds=30 ./profiles/server/allocs.base.pprof

Тут видно что больше всего памяти потребляет compress/flate.NewWriter.

client

mkdir -p ./profiles/client
curl http://localhost:8081/debug/pprof/allocs > ./profiles/client/allocs.base.pprof
# go tool pprof -http=":9090" -seconds=30 http://localhost:8081/debug/pprof/allocs
go tool pprof -http=":9090" -seconds=30 ./profiles/client/allocs.base.pprof

Тут видно что больше всего памяти потребляет compress/flate.NewWriter.
