In 1987 I sold a minitel server to a teacher union. During spring time they make more than 12000 connections a day. I will replace their old 486DX33/Interactive Unix by a Pentium-133/FreeBSD-2.1-STABLE machine. I also plan to improve the minitel server for the new services; fast minitel and PC accesses. > I think that the expensive part of the pty is going to be there whether > or not you put in the endpoint. > > You may save on fd's doing this, but I think overall the increased code > complexity in the muxed pty driver will steal back whatever savings you > get that way. > An other idea is to add a bit map of opened pty/ttyp in the pty/ttyp driver to speed up the function that find an unopened pty/ttyp. > Something like this will probably be a false economy, unless maybe you > will put *all* of your code in the kernel. > I'm sure that it would be the best solution but I dont have any idea on how to use tcp/ip from inside the kernel. > > Terry Lambert > terry@lambert.org > --- > Any opinions in this posting are my own and not those of my present > or previous employers. > -- Didier Derny didier@aida.org
