It was brought to my attention that "fake router creation" scalability was affected during kernel development.
The following script was used for all the tests and charts generation:
http://people.canonical.com/~inaddy/lp1328088/make_fake_routers.sh
http://people.canonical.com/~inaddy/lp1328088/parse.py
I measured how many "fake routers" (above script) could be added per second from 0 to 4000 created routers mark. Using this script and a git bisect on kernel tree I was led to one specific commit causing regression: #911af505 "rcu: Provide compile-time control for no-CBs CPUs".
It appeared that rcu, rcu callbacks and no-cb cpus were causing the issue so every commit that changed any of this files: "kernel/rcutree.c kernel/rcutree.h kernel/rcutree_plugin.h include/trace/events/rcu.h include/linux/rcupdate.h" was tested. The idea was to check performance regression during rcu development. In the worst case I would have data for performance regression during kernel development (since we have rcu commits from 3.8 to 3.14).
All text below this refer to 2 groups of charts, generated during the study:
1) Kernel git tags from 3.8 to 3.14.
http://people.canonical.com/~inaddy/lp1328088/charts/250-tag.html
2) Kernel git commits for rcu development (111 commits).
http://people.canonical.com/~inaddy/lp1328088/charts/250.html
Since there was difference in results depending on how many cpus or how the no-cb cpus were configured, 3 kernel config options were used on every measure:
- CONFIG_RCU_NOCB_CPU (disabled: nocbno)
- CONFIG_RCU_NOCB_CPU_ALL (enabled: nocball)
- CONFIG_RCU_NOCB_CPU_NONE (enabled: nocbnone)
After charts generation and study it was clear that NOCB_CPU_ALL (4 cpus) affected the "fake routers" creation process performance and this regression continues up to upstream version. It was also clear that, after this commit, there is no scalability executing this test with more than 1 cpu.
Comparing standing out points (see charts):
#81e5949 - good
#911af50 - bad
#6faf728 - not good enough
I was able to see that from the script above the following lines were affected:
1) ip netns add -> huge performance regression
2) ip netns exec -> some performance regression
#
# Assumption
#
rcu callbacks being offloaded to other cpus caused regression in unshare(CLONE_NEWNET) code.
# Specific kernel entry being investigated:
unshare(CLONE_NEWNET) |

Even Though this change was experimental at that point, it introduced a performance scalability regression (explained below) that still last and seems to be the default option for distributions nowadays.
RCU related code looked like to be responsible for the problem. With that, every commit from tag v3.8..master that changed any of this files: "kernel/rcutree.c kernel/rcutree.h kernel/rcutree_plugin.h include/trace/events/rcu.h include/linux/rcupdate.h" was tested. The idea was to check performance regression during rcu development. In the worst case, the regression not being related to rcu, I would still have data to interpret the performance/scalability regression.

Obs: For 1 cpu cases: nocbno, nocbnone, nocball behaves the same since w/ only 1 cpu there is no no-cb cpu
After charts being generated it was clear that NOCB_CPU_ALL (4 cpus) affected the "fake routers" creation process performance and this regression continues up to upstream version. It was also clear that, after commit #911af50, having more than 1 cpu does not improve performance/scalability for netns, makes it worse.

...
Comparing standing out points (see charts):
#81e5949 - good
#911af50 - bad
I was able to see that, from the script above, the following lines causes major impact on netns scalability/performance:
1) ip netns add -> huge performance regression:
1 cpu: no regression
4 cpu: regression for NOCB_CPU_ALL
obs: regression from 250 netns/sec to 50 netns/sec
on 500 netns already created mark
2) ip netns exec -> some performance regression
1 cpu: no regression
4 cpu: regression for NOCB_CPU_ALL
obs: regression from 40 netns (+1 exec per netns
creation) to 20 netns/sec on 500 netns created
mark
# Assumption (to be confirmed)
rcu callbacks being offloaded to other cpus caused regression in copy_net_ns<-created_new_namespaces or unshare(clone_newnet). |

SRU Justification:
Impact: network namespace creation has performance regression since v3.5.
Fix: my analysis, lklm discussion, upstream patch
Testcase:
http://people.canonical.com/~inaddy/lp1328088/make_fake_routers.sh
http://people.canonical.com/~inaddy/lp1328088/parse.py
http://people.canonical.com/~inaddy/lp1328088/charts/250.html
http://people.canonical.com/~inaddy/lp1328088/charts/250-tag.html
Running make_fake_routers.sh 4000 and using parse.py you can check if
"fake routers" are being created in a good rate /sec (and you can
compare with all generated charts).
