ECZ.MEMORY.LEVEL = 4 | n
This parameter identifies how much virtual memory is allocated to maintain the internal compression state. This memory is above the 16 megabyte line. The valid value range is 1–9. The default is 4. Level 1 requires the least memory (1 KB); level 9 requires the most memory (256 KB).
Compression consumes significant CPU resources. For more information, see the caution for the parameter, ECZ.COMPRESSION.LEVEL = 1 | n.
