[Jool-list] Performance scaling

[Alberto Leiva]

Hi

> I was wondering what the limits are for performance scaling for jool. How much traffic (bandwidth/pps) can jool handle?

Sorry; we don't really know. This post, however, might grant some
reference. It looks quite optimistic:

Note, however, that it's only talking about SIIT Jool.

Yes, we have confirmed that the kernel is able to defer packets to
Jool simultaneously:

Some of Jool's code relies on spinlocks, however, so it should not
scale perfectly linearly.

Sorry I'm not being very helpful, but we do not have access to a
real/natural network that is able to push Jool to its limits. We
rather need to rely on our users for this.

Hope I didn't leave you exactly where you started.
