/* 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)
|
|
plus a few kilobytes for small objects. For example, if you want to reduce
|
|
the default memory requirements from 256K to 128K, compile with
|
|
make CFLAGS="-O -DMAX_WBITS=14 -DMAX_MEM_LEVEL=7"
|
|
Of course this will generally degrade compression (there's no free lunch).
|
|

The memory requirements for inflate are (in bytes) 1 << windowBits
|
|
that is, 32K for windowBits=15 (default value) plus a few kilobytes
|

for small objects.
