Should LXC containers run high-load tasks limit CPU per VPS or not?

admin

I have a bunch of high CPU load tasks to run on some LXC containers. These LXC host machines all run the same task.
For example, one host runs ten containers. Should I limit CPU to 1/10 per container for each task or let them compete for CPU time?
These tasks are highly concurrent and can be ignored in terms of single-threaded performance.
