27 The process of compression will consume additional CPU cycles, and the

39 Compression level can be used to control the compression speed and the
40 compression ratio. High compression ratio will take more time, level 0
41 stands for no compression, level 1 stands for the best compression

8 The ``QPL`` compression relies on Intel In-Memory Analytics Accelerator(``IAA``)
115 - 8 engines and 1 work queue are configured in group 0, so all compression jobs
163 The multifd migration with ``QPL`` compression method will use all work
204 4 - Enable ``QPL`` compression during migration
206 Set ``migrate_set_parameter multifd-compression qpl`` when migrating, the
207 ``QPL`` compression does not support configuring the compression level, it
208 only supports one compression level.
