External IO, yes, disk IO, no. QMail allows you to initiate a single spool file with a list of addresses to VERP against, and from there every message is delivered individually. This cuts local disk IO, the ultimate constraining performance factor, drastically.
Except that, as was noted earlier, Chuq's problem *is* his wires. :-)
Umm, those are his wires within his network, not the wires to the great untapped 'network at large. Yeesh. MTAs are fundamentally disk IO bound. No two ways about it. Not much you can do about it either, not without violating the commit semantics of the protocol.
<shrug> Chuq speaks better for himself than I do.

And me, but would it be pertinent to point out here, that it he's melting down Fast-Ethernet, then the size of his uplink pretty much doesn't matter? ;-)
