+1 赞同取消同步写和 pooled 的方式，建议实现 Java 版本的 [multi 连接方式](https://github.com/apache/incubator-brpc/issues/506)。
Profiler is a very important feature for JMH users, hope to support soon :)
@lkj41110 It is a nice feature. Can you emit a PR?
Dubbo has both `gson` and `fastjson` dependencies, It is better to keep only one left.
Plz follow the `readme` and add the samples to test cases
可以尝试下 triple 协议，能够和原生 grpc 互通
Some tests failed
You can try [triple](https://github.com/apache/dubbo-samples/tree/master/dubbo-samples-triple/src) protocol instead, it is fully compatibility with grpc/http2
Triple 服务测试需要统一支持下，包括 go /java 和其他语言的客户端，建议的方式是内置获取元数据的接口，统一命令行或web页面的测试方式，可以参考 grpcurl 和 grpc-ui
请发下报错信息
