  I was told by Denis Tonn that there is an optimum - too many can also
degrade
performance.  For my 96MB system he suggested:
          DiskIdle:    30000 milliseconds
            MaxAge:    60000 milliseconds
        BufferIdle:    15000 milliseconds
        Cache size:     2048 kbytes
3 Lazy write worker(s) are enabled.
1 Read ahead worker(s) are enabled.
Relationship as DiskIdle=2*BufferIdle, Maxage=2(to 5)*DiskIdle
