Found this in /sys/netgraph/ng_base.c. Yes, it does seem to have a pool of worker threads. This is good. It means that if there's a single thread or single CPU bottleneck for a busy PPTP server, it would not be the netgraph traffic but rather the one process handling the TCP control connections for the PPTP sessions. I'll give it a try and see if this causes any problems. Still wondering about that boot time message, though. --Brett
