Did you read /usr/src/linux/Documentation/sysctl/vm.txt? If you have 1G of ram and not many active processes, you might get a *lot* of queueing if your settings are a bit off.
I ran this for you on my favorite overworked Linux box. It processes 50% of the incoming and outgoing mail of ~50.000 cable modem subscribers, without a flaw:
[root@smtpe vm]# uname -a ; for a in * ; do echo $a: ; cat $a; echo ; done Linux smtpe.casema.net 2.2.12-20 #8 Wed Jan 19 14:40:56 CET 2000 i686 unknown
