From my understanding of the OP's post. His requirements were that he should be able to randomly access the file by line number.

It will obviously be slower than a simple sequential read of the file as it has to do that once in order to build teh index. It is only when subsequent use is made to re-read individual records in random order that it will be beneficial.
