Hello,
I'm trying to test out the SMTP/B server. When I go
to configure the SMTP server and set the IP Address, the two IPs available in
the drop down menu do not match the IP that my test machine currently has. Any
ideas/recommendations?
Thanks,
David Droddy

The with a RAM disk is that memory speed is rated in nano
seconds where as
hard disk speeds are rated in mili seconds. So if it is
setup correctly, it
seems to make a lot of sense that it greatly increase
performance of the
POST mod. However, I have not tried it. Thanks for the
pennies !

results
Just thought I would add to this post. In another life,
and some time ago,
I explored Ramdisks
in various configurations. In my
results the bottom line was that it was
the fastest method
for disk IO
bound applications, _as long as there is sufficient CPU
bandwidth
available_. In
other words, the problem just spread elsewhere as now the
CPU had to
actually move memory
around and could not make use of any DMA
devices (directly).
The _absolute_ best method for a RAM disk is an
external device, that
connects via Fibre or SCSI
hi-bandwidth. This way,
all of the I/Os can happen within the original Disk
I/O subsystem.
You
end up with basically zero latency, and the I/O can happen via DMA
access,
while the CPU is
doing other things. Downside was
$$$$.
If you google for "Solid state ram disk" you can find various
products. An
example is:
http://www.superssd.com/products/ramsan-320/index.htm
Please
note that I HAVE NO INTEREST IN THIS COMPANY. I JUST GOOGLED...
But they do
claim 250,000 I/Os per second, with 3 GB/Sec of thruput.
That is a lot of
email...
