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 |
