Pull Request Overview
This PR addresses Issue #3523 by increasing the default connection buffer size from 4 KB to 8 KB.
- Introduces a new constant BUFFER_SIZE set to 8 KB.
- Updates the BytesMut buffer allocation to use the new BUFFER_SIZE.
Comments suppressed due to low confidence (1)

- [nitpick] Consider renaming BUFFER_SIZE to better reflect its purpose (for example, INITIAL_BUF_CAPACITY) and clarifying its distinction from CAPACITY, which is used for framing the TCP stream. This can improve code readability and maintainability.
const BUFFER_SIZE: usize = 8 * 1024; // 8 KB

165-176:send_command_refunexpectedly mutates the caller’sRemotingCommandCalling
take_body()removes the body from the original command, so the caller ends up with an empty body after the send. For a&mutAPI this side-effect is surprising and may break retry logic.Fix ideas:
- Clone the body instead of taking it.
- Change the function docstring to explicitly warn that the body is consumed.
- Remove this API and require callers to pass ownership (
send_command) if they need body consumption.This is behaviourally significant; please double-check the intended semantics.

101-103: Extract the new 8 KB constant to the module level for easier reuse
BUFFER_SIZEis declared insideConnection::new, which hides it from the rest of the module.
Defining it at the top level keeps magic numbers in one place and lets other helpers (e.g. unit tests or alternative constructors) reuse the value without duplication.- const BUFFER_SIZE: usize = 8 * 1024; // 8 KB +// Initial capacity for the per-connection encode buffer. +pub(crate) const BUFFER_SIZE: usize = 8 * 1024; // 8 KBThen inside
new:- buf: BytesMut::with_capacity(BUFFER_SIZE), + buf: BytesMut::with_capacity(BUFFER_SIZE),
144-154:send_commandandsend_command_refshare identical serialization logicThe only difference is ownership of
command. Extract the common code into a private helper to avoid future drift.pub async fn send_command( - &mut self, - mut command: RemotingCommand, - ) -> rocketmq_error::RocketMQResult<()> { - self.buf.clear(); - command.fast_header_encode(&mut self.buf); - if let Some(body_inner) = command.take_body() { - self.buf.put(body_inner); - } - self.writer.send(self.buf.clone().freeze()).await?; - Ok(()) - } + &mut self, + mut command: RemotingCommand, +) -> rocketmq_error::RocketMQResult<()> { + self.serialize_and_send(&mut command).await +}…and do the same in
send_command_ref.This removes duplication and makes future buffer-size changes one-line edits.

109-110: LGTM – bigger initial buffer should reduce small reallocationsThe switch from 4 KB to 8 KB is low-risk and will cut the number of reallocations for medium-sized messages. 👍
