Public bug reported:
If there are many networks when using metaplugin, net-list (GET networks API)
takes very long time.
For example: (showing hardware spec etc. is omitted since it is relative
comparison.)
--- 200 networks, openvswitch plugin used natively
$ time neutron net-list
...snip
real 0m2.007s
user 0m0.428s
sys 0m0.100s
---
--- 200 openvswitch networks, under metaplugin
$ time neutron net-list
...snip
real 0m7.700s
user 0m0.472s
sys 0m0.072s
---
Note that the quantum-server wastes a lot of cpu usage too.
