Is your RPC a client-streaming or bidirectional RPC? If not, you're not going to see much benefit from isReady on client-side.
isReady() will become true before the server actually sees the RPC. There is buffering done in gRPC to allow for adequate throughput, so the isReady() is not precisely 1:1 between request() on server-side. There is a hard-coded buffer of 64 KB and the default window size is 1 MB, so if you are sending less than 1 MB, isReady() won't limit you much. (You can change the window size though on the channel builder.) In the future we'd like to auto-tune the window to be able to push-back earlier. If that doesn't explain the behavior you're seeing, then it'd be good to know more about the streams you're dealing with.
