[PATCH] zlib changes: memlevel

Jörn Engel · Linus Torvalds · commit 5b29b6f30e73 · 2003-06-08T04:11:10.000-07:00
Reduce MAX_MEM_LEVEL to 8.  This reduces zlib memory consumption by
128k (from ~400k to ~270k) at the theoretical cost of worse
compression.  No code currently in the kernel actually uses the better
compression, so the practical cost is zero.
