Dear developers,
Please read this thread:
http://lists.freebsd.org/pipermail/freebsd-net/2008-May/017891.html
I'm using no encryption and no compression in mpd, so netgraph should fly.
It seems to get bad after 500 sessions...
In FreeBSD 6 - it's swi1: net - 100% CPU
In FreeBSD 7 - it's em0 taskq - 100% CPU
After playing with it I can make guess that's a netgraph problem.
Maybe it's a poor design in netgraph the way it handle its tables and
it's is probably not designed to add so many interfaces.
Might be there something in the source code I can edit to improve the
table lookups or hash table or whatever netgraph use to store and
process the node information and do the ppp/gre work.
