pysockmmsg

Python wrappers for Linux's sendmmsg and recvmmsg system calls.

When sending/receiving a large amount of packets, preparing the data to be send/received using only a single system call can improve a lot the overal performance by reducing kernel/userland context switching.

Install it from PyPI

pip install pysockmmsg

Usage

Sending multiple messages at a time

import socket
from pysockmmsg import sendmmsg

data_to_send = {
    ('10.10.1.20', '5555'): [b"msg1", b"msg2", b"msg3"],
    ('10.10.1.25', '5555'): [b"msg4", b"msg5"],
    ('10.10.1.26', '5555'): [b"msg6", b"msg7", b"msg8", b"msg9"],
}

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sendmmsg(sock, data_to_send, total_packets=9)
