Your problem is not the vnode limit, but nullfs.
https://people.freebsd.org/~mjg/netchild-periodic-find.svg
122 nullfs mounts on this system. And every jail I setup has several
null mounts. One basesystem mounted into every jail, and then shared
ports (packages/distfiles/ccache) across all of them.
First, some of the contention is notorious VI_LOCK in order to do
anything.
But more importantly the mind-boggling off-cpu time comes from
exclusive locking which should not be there to begin with -- as in
that xlock in stat should be a slock.
Maybe I'm going to look into it later.
That would be fantastic.
Bye,
Alexander.
