Well, just heard from an ISP that they're going to replace their freebsd
news server with an l***x one because the current system is not stable under
high loads.  With 64 MB of RAM, NetBSD seems to be doing reasonably well as
a news server, except that the disk IO is slow because the system uses so
little RAM for the disk cache.
