| 17 | %description | |
| 18 | Lbzip2 is a Pthreads-based parallel bzip2/bunzip2 filter, passable to | |
| 19 | GNU tar with the --use-compress-program option. | |
| 20 | ||
| 21 | It isn't restricted to regular files on input, nor output. Successful | |
| 22 | splitting for decompression isn't guaranteed, just very likely | |
| 23 | (failure is detected). Splitting in both modes and compression itself | |
| 24 | occur with an approximate 900k block size. | |
| 25 | ||
| 26 | On an Athlon-64 X2 6000+, lbzip2 was 92% faster than standard bzip2 | |
| 27 | when compressing, and 45% faster when decompressing (based on wall | |
| 28 | clock time). | |
| 29 | ||
| 30 | Lbzip2 strives to be portable by requiring UNIX 98 APIs only, besides | |
| 31 | an unmodified libbz2. | |

| 34 | Lbzip2 to oparty na bibliotece Pthreads zrównoleglony filtr | |
| 35 | bzip2/bunzip2, który można przekazać do GNU tara przy użyciu opcji | |
| 36 | --use-compress-program. | |
| 37 | ||
| 38 | Lbzip2 nie jest ograniczony do zwykłych plików na wejściu ani na | |
| 39 | wyjściu. Nie jest gwarantowany podział przy dekompresji, ale jest on | |
| 40 | bardzo prawdopodobny (niepowodzenie jest wykrywane). Podział w obu | |
| 41 | trybach oraz sama kompresja jest wykonywana z rozmiarem bloku około | |
| 42 | 900k. | |
| 43 | ||
| 44 | Na procesorze Athlon-64 X2 6000+ lbzip2 okazał się 92% szybszy od | |
| 45 | standardowego programu bzip2 przy kompresji, a 45% szybszy przy | |
| 46 | dekompresji (jeśli chodzi o czas rzeczywisty). | |
| 47 | ||
| 48 | Lbzip2 powinien być przenośny, jako że wymaga tylko API UNIX 98 (poza | |
| 49 | samą, niezmodyfikowaną biblioteką libbz2). | |
