Namespace: System.Workflow.Runtime.Hosting
Assembly: System.Workflow.Runtime (in system.workflow.runtime.dll)
Syntax
Visual Basic (Declaration)
Public Sub New ( _
maxSimultaneousWorkflows As Integer _
)
Dim maxSimultaneousWorkflows As Integer
Dim instance As New DefaultWorkflowSchedulerService(maxSimultaneousWorkflows)
public DefaultWorkflowSchedulerService (
int maxSimultaneousWorkflows
)
public:
DefaultWorkflowSchedulerService (
int maxSimultaneousWorkflows
)
public DefaultWorkflowSchedulerService (
int maxSimultaneousWorkflows
)
public function DefaultWorkflowSchedulerService (
maxSimultaneousWorkflows : int
)
Parameters
- maxSimultaneousWorkflows
An integer that determines the maximum number of workflow instances that can be stored in the thread pool queue.
Exceptions
Remarks
Setting maxSimultaneousWorkflows to a high value may cause the .NET thread pool to starve. This could cause timeouts when a persistence service tries to complete a persistence transaction because Transaction objects also use the .NET thread pool.
If not specified in a constructor or configuration file, the default value for maxSimultaneousWorkflows is 5 for a single-processor machine, and (int)(5 * Environment.ProcessorCount * .8) for a multiple-processor machine. Note that (int)(5 * Environment.ProcessorCount * .8) isn't always the same as (int)(4 * Environment.ProcessorCount), because of the rules of integer arithmetic.
