Performance
MSDE 2000 is a local data engine that can be shared. It has a managed
concurrency workload governor that limits up to five concurrent batch
workloads for optimal performance. Commands and log entries are available to
monitor instances where more than five workloads are executed concurrently,
a situation that can cause slower performance even on well-tuned systems. As
more batch workloads are submitted beyond the five-workload limit, the
concurrency governor continues to slow down the system. These workloads are
not dropped or lost; they are still processed, but in an increasingly
degraded performance mode. If your solution must support more than five
concurrent workloads, it is highly recommended that you migrate to SQL
Server 2000 or SQL Server 2000 Enterprise Edition for optimal performance at
this higher level of scalability.
