GEODE-5043: Buffering protobuf output to avoid multiple packet sends (#1768)
GEODE-5043: Buffering protobuf output to avoid multiple packet sends
Based on the stats all protobuf requests and responses were being sent
as two packets. Using a BufferedOutputStream to make sure we only send 1
packet
> Protobuf server and client are sending multiple packets for a single request

> While doing some performance testing, we discovered that the protobuf client
> and protobuf server are actually sending multiple packets per request and
> response based on the the LinuxSystemStats.xmitPackets. The messages are
> small enough they should fit in a single packet.
>
> Looking at the code, it looks like in both the client and the server we are
> writing directly to socket.getOutputStream(). As soon as data is written to
> that outputstream it could be sent to the the remote side. Wrapping that in
> the BufferedOutputStream eleminates the duplicate packets and improves the
> performance.
