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