rpc performance test

multi client request-response between rust and kotlin on android

conclusion

  1. kotlin serialization json encode bytearry is very slow
  2. android bitmap png compression too slow
  3. tarpc with bincode serialization: 50ms to transfer image 4x1080x1920
  4. with png encode decode is slower: 110ms
  5. tcp or uds have no obvious differences

reproduce

start server: run app in android studio

start client

cd client
./0.sh run

exp

communication strategy:

  1. kotlin http server, ktor, json serialization
  2. kotlin grpc server, OkHttp, protobuf serialization
  3. axum + jni, http/tcp, json serialization
  4. axum + jni, uds, json serialization
  5. axum + jni, tarpc over http/tcp, json serialization
  6. axum + jni, tarpc over uds, json serialization
  7. axum + jni, tarpc over uds, bincode serialization

not test:

  1. tonic: grpc, protobuf serialization
  2. capnp-rpc: client call is builder style
  3. jsonrpsee: assume it's same as tarpc with json serialization
  4. serde-byte: need try on our image buffer

time: duration of request response decode at client

task: get screenshot, get screennode, click position
