One big call vs. multiple smaller TSQL calls
- by BrokeMyLegBiking
I have a ADO.NET/TSQL performance question. We have two options in our application:
1) One big database call with multiple result sets, then in code step through each result set and populate my objects. This results in one round trip to the database.
2) Multiple small database calls.
There is much more code reuse with Option 2 which is an advantage of that option. But I would like to get some input on what the performance cost is. Are two small round trips twice as slow as one big round trip to the database, or is it just a small, say 10% performance loss? We are using C# 3.5 and Sql Server 2008 with stored procedures and ADO.NET.
