Subject: [iproute PATCHv2 0/2] Netns performance improvements
Date: Tue, 5 Jul 2016 16:51:18 +0200 [thread overview]
Message-ID: <1467730280-17493-1-git-send-email-phil@nwl.cc> (raw)
Stress-testing OpenStack Neutron revealed poor performance of 'ip netns'
when dealing with a high amount of namespaces. The cause of this lies in
the combination of how iproute2 mounts NETNS_RUN_DIR and the netns files
therein and the fact that systemd makes all mount points of the system
shared.
Changes since v1:
- Added Suggested-by tag to patches.
Phil Sutter (2):
ipnetns: Move NETNS_RUN_DIR into it's own propagation group
ipnetns: Make netns mount points private
