I developer a WinForm application which connect via Internet to SQL Server 2008. I expect huge use of the application and I want to minimize network traffic as some users will be with mobile internet. I use SQL Server Native Client 10.0 OLE DB Provider with SQLDatareader.
I’m interesting; does SQL Server do any compression with network traffic? I mean for example, if I have SQLDatareader which open query with 100 rows and in this 100 rows one string column is have 2-3 values only – it make compression or not? Or may be TCP/IP protocol make compression for all ?
I wonder, if will have effect to use follow technique – the client application first to get strings and its corresponding ID (int) and then the big query to return only ID instead of string. If there is not compression while the data is transferred I know this will pay back the additional effort, that is why the question.
Open a compress VPN connection is not option for my case.
