Depends on what you want to do with the data in the file. You will need to explain what kind of file this is regarding, and what information you would want to extract.

Just trying to read the file right off will be slow no matter what language you use.

You should first try with SMALL files (e.g. 100-200 MB)

opening the file in binary mode, and reading it into several text variables.
