| 8 | If connecting to a Virtual Machine using the Microsoft RDP
|
|---|
| 9 | client, called a Remote Desktop Connection, there can be large
|
|---|
| 10 | delays between input such as moving the mouse over a menu and
|
|---|
| 11 | output. This is because this RDP client collects input for a
|
|---|
| 12 | certain time before sending it to the RDP server.
|
|---|
| 13 | </p>
|
|---|
| 14 | <p>
|
|---|
| 15 | The interval can be decreased by setting a Windows registry key
|
|---|
| 16 | to smaller values than the default of 100. The key does not
|
|---|
| 17 | exist initially and must be of type DWORD. The unit for its
|
|---|
| 18 | values is milliseconds. Values around 20 are suitable for
|
|---|
| 19 | low-bandwidth connections between the RDP client and server.
|
|---|
| 20 | Values around 4 can be used for a gigabit Ethernet connection.
|
|---|
| 21 | Generally values below 10 achieve a performance that is very
|
|---|
| 22 | close to that of the local input devices and screen of the host
|
|---|
| 23 | on which the Virtual Machine is running.

| 26 | Depending whether the setting should be changed for an
|
|---|
| 27 | individual user or for the system, set either of the following.
