There is information on exim tuning in the archives.

However, unless there is something really strange in your
configuration the normal information is:-

   1. Get a *really* good disk subsystem.  Email does synchronous
      writes to the disk.


2. *Really* get a good disk subsystem

3. If the mail is disposable use a RAM disk system instead

   4. Tune other things... add memory, cache DNS on the local
      network.  Make sure db lookups are efficient.


Step 4 may get you a few % improvement. Step 1/2 could improve things
by several orders of magnitude.
