Pretty typical scenario for default settings, 2-3x faster, sometimes at a slight compression loss. This provides a much better "default" trade-off than the stdlib.

For people regretting the 0.6% loss the higher compression levels can be used.

Decompression typically has even bigger margin, but it depends on the input.
