EnableCompressionEnableCompression

EnableCompression 指定 Microsoft ReadyBoost™ 快取是否使用壓縮。EnableCompression specifies whether the Microsoft ReadyBoost™ cache uses compression.

停用壓縮後，可以提高 CPU 使用量，並減少耗電量。Disabling compression can improve CPU usage and decrease battery consumption.

啟用壓縮可能需要使用的 RAM 或快取的空間，以確保必要的頁面，可以儲存很少的系統。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.

  • 可攜式電腦有 1 gb 的 RAM，建議使用至少 4 GB 的快取大小中的快速內部的快閃裝置，以避免需要快取壓縮。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.

  • 可攜式電腦有 2 GB 或更多的 RAM，建議使用至少 8 GB 的快取大小中的快速內部的快閃裝置，以避免需要快取壓縮。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.
