| 14 | %description | |
| 15 | Lbzip2 is a Pthreads-based parallel bzip2/bunzip2 filter, passable to | |
| 16 | GNU tar with the --use-compress-program option. | |
| 17 | ||
| 18 | It isn't restricted to regular files on input, nor output. Successful | |
| 19 | splitting for decompression isn't guaranteed, just very likely | |
| 20 | (failure is detected). Splitting in both modes and compression itself | |
| 21 | occur with an approximate 900k block size. | |
| 22 | ||
| 23 | On an Athlon-64 X2 6000+, lbzip2 was 92% faster than standard bzip2 | |
| 24 | when compressing, and 45% faster when decompressing (based on wall | |
| 25 | clock time). | |
| 26 | ||
| 27 | Lbzip2 strives to be portable by requiring UNIX 98 APIs only, besides | |
| 28 | an unmodified libbz2. | |
