c# - StreamWriter automatically flushing buffer when given large messages

Overview

I have a Client-Server whereby I have the streamWriter.WriteLine(messageToClient);on the server sending large messages. The streamReader.ReadLine(); on the client is reading the 2000 length messages fine.

The issue here is the streamWriter.Flush() has no affect on the larger messages, because what I am aiming for is the server to be able to switch between the buffers flushing directly (having a fluid server message output) and not (the server response would be jumbled together until it reaches the buffers limit to flush).

Question: I am thinking that the buffers are auto flushing because they are full? Is so what is the streamWriters max buffer size?

I have tested using much smaller messageToClient and the not flushing of the stream works as intended. Aka the server stream outputs a group of small messages at once to the client, presumably because the buffer was full.

Have you tried using the constructor that takes the buffer size as an argument?

public StreamWriter(
    Stream stream,
    Encoding encoding,
    int bufferSize
)

Edit: poking around in reflector it looks like the default buffer size is 1024 bytes.
