How to write super-fast file-streaming code in C#?

Question

I have to split a huge file into many smaller files. Each of the destination files is defined by an offset and length as the number of bytes. I\'m using the following code:<

Answer 1

No one suggests threading? Writing the smaller files looks like text book example of where threads are useful. Set up a bunch of threads to create the smaller files. this way, you can create them all in parallel and you don't need to wait for each one to finish. My assumption is that creating the files(disk operation) will take WAY longer than splitting up the data. and of course you should verify first that a sequential approach is not adequate.
