threads num = concurrency * 2 + xxx

[zuobe...@gmail.com]

Hi，I have a question.

Why is the number of envoy threads doubled when I set --concurrency, 

for example, when I set：envoy-static -c envoy.yaml --log-path ./error.log --log-level trace --concurrency 64 , 

There are 142 threads in total

By default you should have another N+1 Google grpc client thread, where N = concurrency.

$ sudo eu-stack -p `pgrep envoy` | fgrep "Function_handler"  | awk '{print $5}' |sort |uniq -c
     49 Envoy::Grpc::GoogleAsyncClientThreadLocal::GoogleAsyncClientThreadLocal(Envoy::Api::Api&)::$_0>::_M_invoke(std::_Any_data
      1 Envoy::Server::GuardDogImpl::start(Envoy::Api::Api&)::$_3>::_M_invoke(std::_Any_data
     48 Envoy::Server::WorkerImpl::start(Envoy::Server::GuardDog&)::$_3>::_M_invoke(std::_Any_data
