Indexing
LiveLinq uses indexing and other optimizations to speed up LINQ queries in memory. Speed gains can be hundreds and even thousands of times on queries with high selectivity conditions. Typical/average gains are lower but still significant, a 10-50 times speedup can be considered typical.

Support for Live Views to LINQ
Live view is a LINQ query result that is kept constantly up-to-date without re-populating it every time its base data changes. This makes LiveLinq extremely useful in common data-binding scenarios where objects are edited and may be filtered in or out of views, have their associated subtotals updated and so on. They bridge the gap between data and logic, and can make data-centric applications much simpler and more efficient.

Data Binding
LiveLinq not only accelerates typical queries, but it also allows you to use LINQ in data binding scenarios that would not be possible with standard LINQ.
