Need to see some code really, what type of file, what are you doing with the file

Could be...

* Dodgy code that could be refactored to speed things up
* Network related performance issues
* Hardware related performance issues

Need more info!

Are you talking about editing in the Visual Studio editor? (seeing how you tagged this question)

You need to provide more details on what type of file, which language you want to do it, etc.

You really do not provide much information other than the fact you have a "large file". That is such a subjective value I won't go there.

First, how large is the file? What type of file? Say it is a flat file with 150,000 records. You could put up a splash screen and suck the whole thing into memory then walk through it that way. Not efficient but better than processing a flat file directly.

You could consider sucking up the flat file and loading it into a database. That could speed up processing and make your logic easier.

It could be you have just written bad code. Show us what you are doing and you will get a better answer.
