Thanks the response and explanation James.
I get the following, sooo... not _too_ bad I guess from that perspective.
[k...@bottlenose ~]$ free
total used free shared buffers cached
Mem: 2072908 1987788 85120 0 171084 1096132
-/+ buffers/cache: 720572 1352336
Swap: 4192944 112 4192832
So I guess I need to look elsewhere as to why my experience is "slow".
To clarify my thinking, my 'slow' experience relates to the
Server/Router routing to/from the hosts behind it.
Hosts behind the box timeout frequently when contacting the mail server.
Likewise HTTP calls through the box seem unusually slow despite an
ADSL2+ running at ~ 15Kbps D'Load connection (noise margin and
attentuation seem in reasonable levels). Yet an HTTP call from the
Server itself loads fairly quickly.
'route' shows what it needs to show. I have only ever read of one param
in sysctl.conf that relates to routing. Where do I start to look?

You haven't mentioned swap though - is your machine eating into swap?
The best solution though is to get more RAM. It's cheap, and it makes
everything faster.
That is, assuming this is actually your problem....

Hi Slugger's
It appears I need a lesson in Linux and memory management.
If you could treat this request as if coming from a complete numpty please, and
simply explain the differences between Cached, Buffered and Application Memory
as they pertain to Linux?
According to KDE SysGuard, my CentOS 5.2 server appears to "cache" its entire
2GB quotient of physical RAM. And my general experience of the box (implemented as file
server, mail server, firewall and router) is that it is slow.
Something tells me it shouldn't be behaving like this?
