We've had problems in the past - not full queues though, the disks have
never filled up - but generally I do 2 things:
1) run 'top' if you have it to see if anything is obviously killing the
system - check %idle, %iowait, and the CPU, SIZE/RES columns.
2) On the Sun systems I run 'iostat -xnp 10'. This basically shows how busy
your disks are - if the mail pool is running at 100% busy then yup, delivery
will be slow. Next is to find out why its so busy.
If it really is bad then run 'exiwhat' as root to see what it says. Can't
remember now (its in the manual) but it either shows the output on the
screen or logs it to spool/exim-process.info (I think).
