C# Optimisation: Inserting 200 million rows into database

Question

I have the following (simplified) code which I\'d like to optimise for speed:

long inputLen = 50000000; // 50 million 
DataTable dataTable = new DataTable();
Dat         


        

Answer 1

You should not construct entire datatable in memory. Use this overload of WrtieToServer, that takes array of DataRow. Just split in chunks your data.
