[JBoss JIRA] (JGRP-2504) Poor throughput over high latency TCP connection when recv_buf_size is configured

by Andrew Skalski (Jira)

[ https://issues.redhat.com/browse/JGRP-2504?page=com.atlassian.jira.plugin... ] Andrew Skalski commented on JGRP-2504: -------------------------------------- Here's what I found based on further research. The Linux kernel manages the TCP receive window in two different ways (this is a simplification) depending on whether or not the SO_RCVBUF socket option was explicitly set by the application. By default, the kernel automatically manages the receive buffer and window clamp (an internal per-socket variable that acts as a ceiling on window size) based on the min/default/max sizes defined in the net.ipv4.tcp_rmem sysctl. If the application explicitly configures SO_RCVBUF, this automatic management is disabled. The window clamp is initialized once at handshake time, and does not change, even if SO_RCVBUF is subsequently updated. In the case where the application configures SO_RCVBUF "too late" (after the handshake), the socket ends up in a state where: * Window clamp was initialized based on a small default value * Automatic growth of window clamp is disabled Consequently, throughput is actually worse than if SO_RCVBUF was left unconfigured. (This also explains why recent versions of JGroups performed better for me _by default_ than older versions: the builtin default value for recv_buf_size was removed.) Regarding whether or not the SO_RCVBUF setting is inherited from the listening socket, I found this in chapter 7 of _UNIX Network Programming, Volume 1: The Sockets Networking API, Third Edition_: {quote}The following socket options are inherited by a connected TCP socket from the listening socket (pp. 462–463 of TCPv2): {{SO_DEBUG}}, {{SO_DONTROUTE}}, {{SO_KEEPALIVE}}, {{SO_LINGER}}, {{SO_OOBINLINE}}, {{SO_RCVBUF}}, {{SO_RCVLOWAT}}, {{SO_SNDBUF}}, {{SO_SNDLOWAT}}, {{TCP_MAXSEG}}, and {{TCP_NODELAY}}. This is important with TCP because the connected socket is not returned to a server by {{accept}} until the three-way handshake is completed by the TCP layer. To ensure that one of these socket options is set for the connected socket when the three-way handshake completes, we must set that option for the listening socket. {quote} > Poor throughput over high latency TCP connection when recv_buf_size is configured > --------------------------------------------------------------------------------- > > Key: JGRP-2504 > URL: https://issues.redhat.com/browse/JGRP-2504 > Project: JGroups > Issue Type: Bug > Affects Versions: 5.0.0.Final > Reporter: Andrew Skalski > Assignee: Bela Ban > Priority: Minor > Fix For: 5.1 > > Attachments: SpeedTest.java, bla5.java, bla6.java, bla7.java, delay-ip.sh > > > I recently finished troubleshooting a unidirectional throughput bottleneck involving a JGroups application (Infinispan) communicating over a high-latency (~45 milliseconds) TCP connection. > The root cause was JGroups improperly configuring the receive/send buffers on the listening socket.

Because the issue is a too-small TCP receive window, throughput is ultimately latency-bound. -- This message was sent by Atlassian Jira (v7.13.8#713008)
