Sets the minimum latency that must exist between client and server before transparent caching functions are utilized.

   [-LatencyMilliseconds] <UInt32>

Description

The Set-BCMinSMBLatency cmdlet sets the minimum latency that must exist between client and server before transparent caching functions are utilized. Use this cmdlet to specify when client computers in branch offices start caching content from content servers based on the network latency, or delay, that occurs when the clients download content over a Wide Area Network (WAN) link. When a value for this cmdlet is specified, which is the maximum round trip network latency allowed before caching begins, clients do not cache content until the network latency reaches the specified value; when network latency is greater than the value, clients begin caching content after they receive it from the content servers.

For example, if the round trip network latency value is set to zero (0), the client computers always cache content that they receive from the content servers, no matter how high or low the network latency is between their request for a file and their receipt of the file from the content server. In another example, if the round trip network latency value is set to 100 milliseconds, then the clients do not cache content that they receive before 100 milliseconds pass, but they do begin to cache content that they receive after 100 milliseconds pass.

By default, the value of this setting is 80 milliseconds. To ensure that client computers always cache content, set the network latency value to 0.

To prevent caching except in circumstances where network latency is extremely long, set the latency value to a very high value. If a high value is used, however, then it is possible that network latency will not reach this long a delay, in which case BranchCache is disabled on your network.

Whether this setting is disabled or not configured, the client computer will cache network files if the round trip network latency of the wide area network (WAN) link is above 80 milliseconds.

Examples

EXAMPLE 1

PS C:\>Set-BCMinSMBLatency -LatencyMilliseconds 20

This example sets the minimum latency that must exist between client and server before transparent caching functions are utilized to 20 milliseconds.

Parameters

-AsJob

ps_cimcommon_asjob

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSessionhttp://go.microsoft.com/fwlink/p/?LinkId=227967 or Get-CimSessionhttp://go.microsoft.com/fwlink/p/?LinkId=227966 cmdlet. The default is the current session on the local computer.

Type:CimSession[]
Aliases:Session
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Aliases:cf
Position:Named
Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Force

Runs the cmdlet without prompting for confirmation.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-LatencyMilliseconds

Specifies the minimum latency that must exist between client and server before BranchCache begins caching content.

Type:UInt32
Position:1
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False

-ThrottleLimit

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Type:SwitchParameter
Aliases:wi
Position:Named
Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False

Inputs

None
