DataSource for Entity Framework in WPF > Programming Guide > LiveLinq Query Performance: Tuning Indexing Performance |
Query speedup achieved on any particular query by LiveLinq using indexes for optimization depends on how that query is written. This dependence is usually not dramatic. LiveLinq does a fair job of recognizing opportunities to use indexes for optimization regardless of the way the query is written. For example, it will still execute a query efficiently using indexes even if the condition consists of multiple terms connected with logical operators.
