Asterisk version is from Trixbox v2.2 install CD.  Fairly recent, but 
not positive which version and my machine is currently running memtest 
so I cannot check it right now.

The box is running 2.5 Gb RAM, an Athlon XP running at 1.6 Ghz, a brand 
new Seagate 500 Gb SATA HD.  Interestingly, I have never been conscious 
of the bandwidth available to the various caches and memtest is showing 
the following for this fairly old system:

L1 Cache: 128k 10209MB/s
L2 Cache: 256k  3250MB/s
Memory: 2560M 1015MB/s

This seems to indicate that on the Athlon XP platform, you have a 
Gigabye of bandwidth to RAM, 3 Gigabyte bandwidth to the L2 Cache and 10 
Gigabytes of bandwidth to the L1 cache.  Since PCI (32 bit/ 33 Mhz) 
gives you about a Gigabit of bandwidth total to the periferals, this is 
fairly quick.  I might have to run this CD on my desktop machine which 
is an Athlon 64 and see what it reports in the way of Memory bandwidth 
there.
