Hi dan. Just out of curiosity what leads you to think its I/O?
Is this sending or receiving? You say its on one partition? Is the mail
spool directory hashed? How many mail's are you doing a second? How many
mails WERE you doing a second on linux? A little more insight into how
things are configured would help a bit. :-) I bet brad will see
this too and he will surely know the right direction to point you.
I run mostly postfix here. Since it has lower overhead writing mail.
If your queue is being filled up because qmail isnt processing
them fast enough that mostly sounds just like a configuration problem.
But again I dont know what your traffic is like. If its something small or
something crazy.
