yes, I already tmpfs for the work dir. I am thinking that with 10,000
mails in the mqueue.in directory (~20000 files) the system might be
stalling just reading the dir.

I've just increased max children from 9 to 20 to see if that helps. The
comments recommend 5 per cpu but doesnt mention HT processors.
