Specifies how much memory should be allocated for the internal compression state. 1
uses minimum memory but is slow and reduces compression ratio; 9
uses maximum memory for optimal speed. The default value is 8
.
The memory requirements for deflate are (in bytes):
(1 << (windowBits + 2)) + (1 << (memLevel + 9))
that is: 128K for windowBits = 15 + 128K for memLevel = 8 (default values)
final int memLevel
