We also have patches in the works to allow full kernel bypass of the ppp daemon in the common case, resulting in Mucho performance increase. with the version we have now, a 100KB/sec ppp session took 6% of a P6-200 (the other end was a 486DX50 :-) with enough RAM we could probably serve 10K sessions, though that would require 10K ppp daemons until we got the kernel bypass working. in either case it would presently leave a HUGE ifconfig -a output as there would be 10000 intefeaces, each representing a channel to a client. It migh tbe worth wondering if we need to abstract a 'class of PVCs' type device that feeds to some othe rway of splitting them. (we can do this with netgraph pretty easily.) (is it worth doing?)
