10 in memory itself. These disks allow very fast I/O and compression provides
73 2) Set max number of compression streams
77 allocate multiple compression streams - one per online CPUs - thus
78 allowing several concurrent compression operations. The number of
79 allocated compression streams goes down when some of the CPUs
80 become offline. There is no single-compression-stream mode anymore,
87 3) Select compression algorithm
91 currently selected (shown in square brackets) compression algorithms,
92 change selected compression algorithm (once the device is initialised
93 there is no way to change compression algorithm).
97 #show supported compression algorithms
101 #select lzo compression algorithm
105 show every compression algorithm supported by the kernel. We keep this
107 a new device with a compression algorithm that is not listed in
112 custom crypto compression modules (implementing S/W or H/W compression).
131 since we expect a 2:1 compression ratio. Note that zram uses about 0.1% of the
