C# Mix 11,000,000 records with high performance

Hi friends,

I want to speed up processing of my windows form app.

Currently my app is good enough but it's slow when to mix a list of 11 millions of records

What the app to do is:

- To read the list of 11 millions of email address (one per line) from text file

- Then to generate new list (file) where 2 continuous lines don't have the same domain in email address

I need anyone smart to make this process faster. My machine has a lot of RAM, 8 Cores CPU but this process costs many hours to complete.

I will not provide list or source code. I will choose the freelancer has good solution for this. I will chat with anyone has a solution in proposal.
