  I have always understood that the bigger the disk cache, the smaller the
benefits.
  If you have 1 MB of disk cache, you will see a big increase in speed.
With 2 MB the speed will increase again, but it will not double. With
4 MB the speed increases a little, but it will be a lot less than 4 times
the speed of 1 MB. The more memory you use for disk caching, the smaller
will the speed/memory-relation be, because you don't get the same benefit
for each MB you add.
  This means that the speed achieved with 40 MB will be aproximately the
same as with 42MB. So you wasted 2 MB for nothing.
