8 in memory itself. These disks allow very fast I/O and compression provides
24 2) Set max number of compression streams
25 	Compression backend may use up to max_comp_streams compression streams,
26 	thus allowing up to max_comp_streams concurrent compression operations.
27 	By default, compression backend uses single compression stream.
