[Mimedefang] ramdisks on Linux

[Aaron Paetznick]

It's become obvious that using ramdisks with MIMEDefang is very 
important.  This might be a strange/silly question, but if I wanted to 
use a ramdisk for both the sendmail mqueue and the MIMEDefang work 
directory, would it be better to use two smaller, or one large ramdisk? 
  Does using two separate ramdisks give the same performance benefit as 
using two separate physical disks?

Also, does the speed of the RAM and memory controller directly affect 
the speed of the ramdisk?  For instance, would a ramdisk on an Intel 
7501 based machine running dual-channel DDR266 be slower than a ramdisk 
on an AMD Opteron 246 based machine (with an on-chip memory controller) 
using dual-channel DDR400?

I'm sorry if this is too off topic for this list.
