hi:
i have encountered a problem that ovs add-port takes long time, can you help
me?
testing enviroment:
CentOS release 6.5 (Final),
Linux l3vpn2 3.16.0-rc1 #1 SMP Mon Jun 16 15:45:19 EDT 2014 x86_64 x86_64
x86_64 GNU/Linux
ovs-vswitchd (Open vSwitch) 1.11.0
Compiled Jul 30 2013 18:14:54
OpenFlow versions 0x1:0x1
testing step:
1. add br0
2. use cmd ovs-vsctl add-port, to add 16K internal ports, each 4 ports are in
the same namespace
problem:
for the first 100~200 ports, system responds quickly; and then it become slower
and slower;
after the total port numbers reached to 8000, it takes about 3 minutes to add
one vport
analysis:
i have read the kernel code, and i don't think it is the reason why ovs
add-port so slowly
i doubt whether the ovsdb is the main reason? and how can i fix the problem?
