EnableCompression

EnableCompression specifies whether the Microsoft ReadyBoost™ cache uses compression.

Disabling compression can improve CPU usage and decrease battery consumption.

Enabling compression may be necessary for systems with a low amount of RAM or cache space, to ensure that the necessary pages can be stored.

• For a portable computer with 1 gigabyte (GB) of RAM, we recommend using a fast internal flash device with a cache size of at least 4 GB, to avoid the need for cache compression.

• For a portable computer with 2 GB or more of RAM, we recommend using a fast internal flash device with a cache size of at least 8 GB, to avoid the need for cache compression.

Values

true	Specifies that the ReadyBoost cache uses compression. This is the default value.
false	Specifies that the ReadyBoost cache does not use compression.

XML Example

The following XML output example shows a configuration of two ReadyBoost devices. On this sample system, the first device does not use compression, while the second device uses compression.
