Parallelizing Data-Intensive Operations
To improve performance for data-intensive operations (sorting, grouping, filtering, summary calculation, etc.), use all the available processors/cores on the system. The GridControl can operate on any in-memory IEnumerable data structure using Parallel LINQ (PLINQ).
There are two DevExpress PLINQ data sources, each designed to address a specific data-processing mode (synchronous and asynchronous).
