For what it's worth, I just ran some tests reading a 4MB file, looping
through line by line and performing some simple math (cnt = cnt + 1)
The java method was CONSISTENTLY around 375ms on my server. I hit
reload like 30 times and it was never below 350ms and never above 500ms,
and almost always below 400ms.
Using CFFILE, it was much more erratic... coming in as low as 450ms but
often coming in at 2000ms and higher.
