Sizing Varnish RAM after over allocation

[Dridi Boukelmoune]

Hi Travis,

I don't see the worker threads (pool and session) workspaces and
stacks in your list. Defaults aren't that high but with a lot of
threads it might become significant. Also, is your system really using
10GB (and not just virtually) ?

Best Regards,
Dridi
