Correct VLF for Transaction log file

Hi Everyone,

We have a database (2.5 Tera Byte), and it is in SQL SERVER 2008 R2,which is being hited heavily.The transaction log file size is 90GB(only 10% of it isbeing used).currently we have 1976 VLF for our transaction log file.What is the best VLF for this database?What are the steps for doing that?

Thanks
