Another important advantage that SQL Server 2005 Express has over MSDE is that it does not have the MSDE workload governor. The MSDE query governor is a widely misunderstood MSDE feature that was intended to limit the type of workloads that MSDE could be used for. The MSDE query governor throttles performance by stalling a user connection for a few milliseconds each time the connection requests a read or write operation on a database when there are more than eight concurrent connections.
