Check some more API (I run these command below from Controller node):
# time quantum subnet-list
(...have 4 subnet)
real    0m0.676s
user    0m0.196s
sys     0m0.020s

# time quantum router-list
(...have 1 router)
real    0m0.496s
user    0m0.164s
sys     0m0.052s

# time nova list --all_tenants=1
(...have 5 instances)
real    0m1.290s
user    0m0.308s
sys     0m0.040s

Compare with my old OpenStack deployment on weaker servers, it took 1/3 in
times.
