A) Because that was the point of the test. Compare cache software under
the SAME conditions. Some can't/won't readahead.
and
B) The test is a REAL test. It runs MUCH faster without readahead.
Readahead collects stuff you don't want/don't need in the cache.
And that's not even the worst part. You have to wait for the disk
to turn to get that stuff. The platter takes 16 milliseconds to make
a full revolution or about 1/2 to 1 mSec a sector. Why wait ?
and
C) The only time readahead improves things is when you are loading a LARGE
file _on a 100% defragged and compacted drive_ for the first time.
