sndbuf-size

The transmission buffer implements the optimization of the transmission amount through buffering. Since TCP/IP transmission is an ACK-based protocol, the more the segment is transmitted, the greater the protocol overhead. Therefore, from a network transmission perspective, it is advantageous to collect and send as much data as possible when sending data. Since the transmit buffer implements this part, optimization can be achieved naturally. In particular, in a situation in which a small amount of data is continuously transmitted, the amount of data can be greatly improved by collecting and sending the data to the transmission buffer queue for a certain amount. You should consider optimizing with sndbuf-size in the following situations:

• When replication target files are divided into small unit files, replication I/O itself occurs as a small unit I/O of 4KB to 8KB.

• Online Verify in small test units

Latency

It covers latency optimization of bsr. To minimize latency, let's review it in terms of hardware and look at some setup options.
