[SPAM-30] howto determine processor characteristics from cli

[Labitt, Bruce]

Jim,

I was trying to figure out if I had a boat anchor, or something worth
the $$$ to add memory.  This is a hand me down machine.  

When I buy new, I always try to max out the RAM.  I know what you mean
about RAM getting expensive.  I had a machine that used RAMBUS.  It was
very fast for its time.  It allowed my 800 MHz CPU to out compute my
later 2.4GHz laptop.  I got a lot of life out of that RAMBUS computer,
must have been a solid 6 years of simulations before there really was
anything much better.

BTW, I did order the memory.  It will allow the cpu in question to eke
by for a few more years.  I really need to get a big machine though, as
I'm memory limited for my simulations.

    To address the core purpose of your query, I always fill up a new 
computer with as much memory as it will take.  If you keep you 
computers for a long time, as I do, the memory gets difficult to find 
and expensive.

    Since disk I/O is the slowest portion of current computers, the more

of the recently used programs or documents the operating system can 
retain in RAM, the faster the computer responds.

    My advice: buy the memory.
