[Newbies] Binary file I/O performance problems

I re-wrote the test application to load the test file entirely into
memory before parsing the data. The total time to parse the file
decreased by about 50%. Now that I/O is removed from the picture, the
new bottle neck is turning bytes into integers (and then integers into
Floats).

I know that Smalltalk isn't the common language for number crunching,
but if I can get acceptable performance out of it, then down the road
I would like to tap into the Croquet environment. That is why I am
trying to learn a way that will work.
