How fast can you create LXC containers?

Question

LXC

Welcome all.
There is a certain project, for the normal functioning of which you need to quickly create a large number of virtual machines or containers and after a short time, compile certain code into them, execute it and extinguish the virtual machines.

I would like to know how fast you can create LXC containers from scratch, and are there any tricks (like copying ZFS zone clones to Solaris) that can speed up this process?

I would also like to hear if there are options for server virtualization that would be better suited for this task.

Thanks in advance for your replies.
