Sorry for taking this long to get back to you, my mailing list filter
needed some adjusting.

I did the steps above, and:

# time lxc-ls --fancy
(...)
real    0m3.926s
user    0m0.531s
sys    0m0.829s

All 100 containers are running.

That's very acceptable. Looks like it's how the containers were created.
