----------------------------------------

             Summary: Set TCP_NODELAY on accepted sockets for Ruby library
                 Key: THRIFT-5904
                 URL: https://issues.apache.org/jira/browse/THRIFT-5904
             Project: Thrift
          Issue Type: Improvement
          Components: Ruby - Library
            Reporter: Dmytro Shteflyuk


Enable {{{{{}TCP_NODELAY}}{}}} flag on the accepted socket in the 
{{{}{{ServerSocket{}}}}} transport in Ruby.

The change brings Ruby server transport to the same level as servers in other 
languages, for example 
[C++|https://github.com/apache/thrift/blob/master/lib/cpp/src/thrift/transport/TServerSocket.cpp#L364-L371].

Benchmark show significant improvement on RPC flows when server is used with 
TLS, as the server tend to sleep a lot of 40ms intervals during TLS handshake 
and then RPC payload transfer.
