I've found that the default rate setting of 10000 gives the client choke,
sometimes up to 40 or so. I don't know how severely this affects gameplay,
but I bumped my sv_maxrate to 20000 some time ago. Using the status command
at the server console shows me that a lot of players use rates higher than
10000, so make of that what you will. In my opinion, choke isn't as big a
factor in a game like Left 4 Dead, but I like keeping my players happy.
20000B/s * 8(clients) = 160KB/s * 8(bits/byte) = 1.28Mbps bandwidth
requirement + a little for overhead. You should be fine with a 1.5Mbps
uplink at a minimum. Obviously, you can halve that if you leave the
sv_maxrate at 10000, but I had versus players complaining about lag when I
limited bandwidth to 768Kb/s for my server. Also, campagin mode requires
less, but that much should be obvious. I see spikes as high as 1.2Mbps on
my single server, so I wouldn't go any less than this unless you won't be
hosting any Versus matches.
After leaving the server running for a week or two, RAM usage never goes
much higher than ~300MB.
CPU usage is also relatively low, but this much will depend upon your system
specs.
