By default zram stores written back pages in decompressed (raw) form, which means that writeback operation involves decompression of the page before writing it to the backing device. This behavior can be changed by enabling -`writeback_compressed` feature, which causes zram to write compressed pages +`compressed_writeback` feature, which causes zram to write compressed pages to the backing device, thus avoiding decompression overhead. To enable this feature, execute:: - $ echo yes > /sys/block/zramX/writeback_compressed + $ echo yes > /sys/block/zramX/compressed_writeback Note that this feature should be configured before the `zramX` device is initialized. |
