2 | - speed up compression by ~10-15% in common cases |

|
|
4 | - import some compiler tricks from JSON::XS. |
|
|
5 | - tune hash functions depending on ULTRA_FAST or VERY_FAST settings. |
|
|
6 | - for typical binary data (e.g. /bin/bash, memory dumps, |
|
|
7 | canterbury corpus etc.), speed is now comparable to fastlz, but |
|
|
8 | with better compression ratio. with ULTRA_FAST, it's typically |
|
|
9 | 3-8% faster than fastlz while still maintaining a similar ratio. |

|
