Mailscanner and server load

[Dave Filchak]

I found this thread to be interesting as I have just had to upgrade my
motherboard and ram because the machine was choking. However, in an effort
to determine how well the machine is doing now, I wonder if someone would be
so kind as to comment on the output of free and vmstat 2 I have posted
below. I was not familiar with these tools so I am not sure how to read them
so if someone would comment on the perceived performance of my machine based
on this output and also a brief explanation of how to interpret this output
(what does it all mean ;-)

Free:

             total       used       free     shared    buffers     cached
Mem:       1014712     966252      48460          0     142552     467144
-/+ buffers/cache:     356556     658156
Swap:      1020088     187928     832160

Vmstat 2:

Thanks,

PS ... Sorry to jump into this conversation but I wanted my question to be
in context.

Is your system swapping?

What is the output of free?

What is the output of

vmstat 2

(ctrl-c to stop, post a few lines)
