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?I don't think you will want to use a ramdisk for the sendmail queue. If you lose power or have to reboot your system, you will lose mail.
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?Since the disk will be in memory, memory performance should make an impact. How much difference though I'm not sure. Probably a lot less difference than going from a disk based work directory to a ramdisk though ..
