EnableCompressionEnableCompression

EnableCompression 指定 Microsoft ReadyBoost™ 缓存是否使用压缩。EnableCompression specifies whether the Microsoft ReadyBoost™ cache uses compression.

禁用压缩可以提高 CPU 使用率并降低电池损耗。Disabling compression can improve CPU usage and decrease battery consumption.

启用压缩可能有必要的系统具有低 RAM 或缓存空间,以确保可以存储所需的页。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.

  • 对于使用 1 千兆字节 (GB) RAM 的便携式计算机,建议使用内部快速闪存设备缓存大小为至少 4 GB,以避免对缓存压缩的需求。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.

  • 对于使用 2 GB 或更大的 RAM 的便携式计算机,建议使用内部快速闪存设备缓存大小为至少 8 GB,以避免对缓存压缩的需求。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.
