Dear developers,

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
unfortunatly I've been totally ignoring this thread because it said
"trouble with em" in the topic..
If you'd said
trouble with mpd then maybe I'd have looked earlier..
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.
how many?
more than 2500
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.
netgraph just had some work done on it for this exact reason,
but you may be jumping the gun a bit..
