But you're only reading, not writing.  19 seconds is in the realm of
possibility.  Here is an example:

~$ ls -l 300megs.txt
-rw-r--r--  1 joe  joe  300000000 Mar  7 07:38 300megs.txt
~$ time cat 300megs.txt > /dev/null

real    0m3.733s
user    0m0.211s
sys     0m2.931s

3.7 seconds to read the file.  This is on a pentium 500 running
FreeBSD with 2 scsi disks striped.  The system is fairly busy serving
up web and crunching data.
