title: Do certain MSTest DataSource providers perform better than others?
body: <p>The MSTest <strong>DataSourceAttribute</strong> supports different data providers for data driven tests (<em>CSV, Excel, SQL, XML, MTM</em>, etc). I'm trying to determine if one is markedly faster or if they all have comparable performance. The MS documentation doesn't seem to address this. I suppose I could profile the different providers but thought I would ask first in case someone had experience with this.</p>
