2 | - switched to GPL v2 or any later version. |
|
|
3 | - speed up compression by ~10-15% in common cases |
|
|
4 | by some manual unrolling. |
|
|
5 | - import some compiler tricks from JSON::XS. |
|
|
6 | - tune hash functions depending on ULTRA_FAST or VERY_FAST settings. |
|
|
7 | - for typical binary data (e.g. /bin/bash, memory dumps, |
|
|
8 | canterbury corpus etc.), speed is now comparable to fastlz, but |
|
|
9 | with better compression ratio. with ULTRA_FAST, it's typically |
|
|
10 | 3-15% faster than fastlz while still maintaining a similar ratio. |
|
|
11 | (amd64 and core 2 duo, ymmv). thanks a lot for the competition :) |
|
|
12 | - undo inline assembly, it is no longer helpful. |
|
|
13 | - no changes to the decompressor. |
