Expand description
How much processing the compressor should do to compress the data.
NoCompression
and Bestspeed
have special meanings, the other levels determine the number
of checks for matches in the hash chains and whether to use lazy or greedy parsing.
Variants
NoCompression
Don’t do any compression, only output uncompressed blocks.
BestSpeed
Fast compression. Uses a special compression routine that is optimized for speed.
BestCompression
Slow/high compression. Do a lot of checks to try to find good matches.
UberCompression
Even more checks, can be very slow.
DefaultLevel
Default compromise between speed and compression.
DefaultCompression
Use the default compression level.
