Projekt GNU je objavil razli\u010dico paketa gzip 1.14, ki vklju\u010duje orodja gzip, gunzip, zmore in zcat za stiskanje in razpakiranje podatkov z algoritmom LZ77. V novi izdaji so bili postopki razpakiranja bistveno pospe\u0161eni. Na sistemih x86_64, ki podpirajo procesorske instrukcije PCLMUL, dose\u017ee pove\u010danje zmogljivosti 40 %, na sistemih brez podpore PCLMUL pa do 20%. <\/p>\n
Pospe\u0161itev je bila dose\u017eena z optimizacijo operacij s kontrolnimi vsotami (CRC), za katere je bilo porabljenih pribli\u017eno polovico procesorskega \u010dasa. Optimizirana razli\u010dica CRC je \u017ee vklju\u010dena v knji\u017enico gnulib, kar bo privedlo do pospe\u0161itev tudi v drugih projektih GNU, ki uporabljajo funkcije za izra\u010dun kontrolnih vsot. <\/p>\n
Spremenjene so bile spremembe, ki kr\u0161ijo zdru\u017eljivost: namestitev orodja zmore je prenehana na platformah, ki ne uporabljajo orodja \u00abmore\u00bb; obdelava okoljske spremenljivke GZIP (dolo\u010da privzete mo\u017enosti) je prene\u0161ana v situacijah, kjer mo\u017enosti \u00ab-1\u00bb (\u2014fast), \u00ab-2\u00bb, \u2026 \u00ab-9\u00bb (\u2014best), \u00ab\u2014rsyncable\u00bb ali \u00ab\u2014synchronous\u00bb niso izrecno navedene. <\/p>\n
Dodatno lahko omenimo: <\/p>\n
