I haven't modified the default values in *.conf files (I'm using devstack
for installation) for workers setting.
How  to check that keystone is using apache with 10 worker process?
And the number of CPU cores on my box is 32.

Just for clarification, regarding the setting of workers option in the
*.conf file:
Fore neutron:
# api_workers = 0

For nova, what option should be set?
I see  these options:
metadata_workers=None(IntOpt)Number of workers for metadata service

I'll try your solution and let you know the result.
