Hello Serge,
I put together a small table, running your script for various values :
Time are in seconds,
Number of veth, time to create, time to delete:
500 18 26
1000 57 70
2000 193 250
3000 435 510
4000 752 824
5000 1123 1185
Obviously it is far from being linear.
Regards
Benoit

Hello Serge,
The time is to create all 5000, not just the last 1000.

Hi
I've began to experiment with lxc by running a ubuntu 12.04 minimal
installation(console-only) inside virtualbox. The default
templates(contained in the lxc distro package) run just fine, but I'm
having trouble getting a simple archlinux container to run. I have
searched the web for a solution
Hi,
Benoit was kind enough to follow up on some scalability issues with
larger (but not huge imo) numbers of containers. Running a script
to simply time the creation of veth pairs on a rather large (iiuc)
machine, he got the following numbers (time is for creation of the
full number, not latest
There I was, minding my own business, running stock lxc on ubuntu 12.04,
when suddenly I couldn't install a perl update inside the container.
Turned out to be it couldn't create a hard link to /usr/bin/s2p
(though it could to /usr/bin/yes):

And it's repeatable, on two different machines, with different kinds
of root filesystems.
This time, the bad file was /usr/bin/psed.
strace shows
link(/usr/bin/psed, /usr/bin/psedxyz) = -1 ENOENT (No such file or
directory)
Same thing if I'm in /usr/bin and try it with relative paths:
Commenting out the line
deb http://security.ubuntu.com/ubuntu precise-security main restricted
universe multiverse
in /etc/apt/sources.list caused the update of perl to not be installed,
and suppressed the problem for now.
I guess I'm living dangerously.
