From e6ea0e5efe82f9e989151a4eb47cc1b1a089aabf Mon Sep 17 00:00:00 2001 From: Emilien Macchi Date: Mon, 16 Jun 2014 14:43:47 +0200 Subject: [PATCH] swift/sysctl: do not disable net.ipv4.tcp_timestamps Turn timestamps off to reduce performance spikes related to timestamp generation. The sysctl command controls the values of TCP related entries, setting the timestamps kernel parameter found at /proc/sys/net/ipv4/tcp_timestamps. It should be enabled in order to make Swift & Ceph working correctly.
