Subject: [PATCH net-next v6 00/10] optimize openvswitch flow looking up
Date: Fri, 1 Nov 2019 22:23:44 +0800 [thread overview]
Message-ID: <1572618234-6904-1-git-send-email-xiangxia.m.yue@gmail.com> (raw)
From: Tonghao Zhang <xiangxia.m.yue@gmail.com>
This series patch optimize openvswitch for performance or simplify
codes.
Patch 1, 2, 4: Port Pravin B Shelar patches to
linux upstream with little changes.
Patch 5, 6, 7: Optimize the flow looking up and
simplify the flow hash.
Patch 8, 9: are bugfix.
The performance test is on Intel Xeon E5-2630 v4.
The test topology is show as below:
+-----------------------------------+
| +---------------------------+ |
| | eth0 ovs-switch eth1 | | Host0
| +---------------------------+ |
+-----------------------------------+
^ |
| |
| |
| |
| v
+-----+----+ +----+-----+
| netperf | Host1 | netserver| Host2
+----------+ +----------+
We use netperf send the 64B packets, and insert 255+ flow-mask:
$ ovs-dpctl add-flow ovs-switch "in_port(1),eth(dst=00:01:00:00:00:00/ff:ff:ff:ff:ff:01),eth_type(0x0800),ipv4(frag=no)" 2
...
$ ovs-dpctl add-flow ovs-switch "in_port(1),eth(dst=00:ff:00:00:00:00/ff:ff:ff:ff:ff:ff),eth_type(0x0800),ipv4(frag=no)" 2
$
$ netperf -t UDP_STREAM -H 2.2.2.200 -l 40 -- -m 18
* Without series patch, throughput 8.28Mbps
* With series patch, throughput 46.05Mbps
v6:
some coding style fixes
v5:
rewrite patch 8, release flow-mask when freeing flow
v4:
access ma->count with READ_ONCE/WRITE_ONCE API. More information,
see patch 5 comments.
v3:
update ma point when realloc mask_array in patch 5
v2:
simplify codes. e.g. use kfree_rcu instead of call_rcu
Tonghao Zhang (10):
net: openvswitch: add flow-mask cache for performance
net: openvswitch: convert mask list in mask array
net: openvswitch: shrink the mask array if necessary
net: openvswitch: optimize flow mask cache hash collision
net: openvswitch: optimize flow-mask looking up
net: openvswitch: simplify the flow_hash
net: openvswitch: add likely in flow_lookup
net: openvswitch: fix possible memleak on destroy flow-table
net: openvswitch: don't unlock mutex when changing the user_features
fails
net: openvswitch: simplify the ovs_dp_cmd_new
