As far as I know it is read in one operation.
 >>> file1 := ReadStream on: file1 contentsOfEntireFile.

There is a tremendous discrepency between Squeak on Windows and Linux.
Windows PII 266 being 33 seconds (with Python at 3 seconds) and Linux 
Athlon 700mhz being .23 seconds (with Python at 1 second).
I'll try my Mac later.
