•A basic explanantion of zRAM•
zRAM compresses an actual block of RAM in order to have more RAM available to the system
If you make the compression too high with zRAM then your device will actually go slower as a result.
zRAM also requires the CPU to compress and decompress the data = Higher Power Consumption
Without ZRAM:
+ CPU Performance | + Battery | RAM
With ZRAM: (beyond 512MB)
CPU Performance |-Battery | + RAM
