Tom qab 11 lub hlis ntawm kev txhim kho thiab tshaj 500 kev cog lus, version 1.5.7 ntawm cov ntaub ntawv ceev ceev compression tsev qiv ntawv thiab cov nqi hluav taws xob hais kom ua Zstandard, sau rau hauv C thiab muab faib raws li BSD thiab GNU GPL 2 daim ntawv tso cai, tau raug tso tawm.
Qhov no yog qhov tseem ceeb tshaj tawm nrog kev txhim kho hauv kev ua haujlwm, kev ruaj ntseg thiab kev ua haujlwm, thiab tshwj xeeb tshaj yog pom zoo rau cov neeg siv 32-ntsis.
Cov kev hloov loj:
- Kho qhov teeb meem ntev ntev thiab tsis tshua muaj compression nyob rau hauv 32-ntsis hom uas tuaj yeem tshwm sim thaum lub sijhawm ntev (tib yam ZSTD_CCtx* tau rov qab siv dua thiab ntau dua).
- Qhov tseem ceeb nce hauv compression ceev (txog + 30%) rau cov ntaub ntawv me.
- Txhim kho compression ceev (~ + 5%) nrog phau ntawv txhais lus ntawm qib compression tsawg.
- Faster --patch-los ntawm kev ua haujlwm ntawm cov qib siab compression, nrog kev txhim kho compression piv.
- Txhim kho compression piv ntawm txhua qib ua tsaug rau kev txhim kho thaiv ciam teb nrhiav kom pom.
- Kev tshawb pom ntawm CPU bmi2 kev qhia ntawm lub sijhawm ua haujlwm tam sim no ua haujlwm hauv 32-ntsis x86 hom thiab.
- Siv multithreading nyob rau hauv lub console utility los ntawm lub neej ntawd.
- Ib qho kev hais kom ua tshiab, --max, tau ntxiv rau lub tshuab hluav taws xob console, uas sim muab qhov zoo tshaj plaws compression piv los ntawm kev thawb tag nrho cov tsis mus rau lawv cov nqi siab tshaj plaws.
- Ib txoj kev tshiab ZSTD_compressSequencesAndLiterals() tau ntxiv rau API.
- Lub ZSTD_getFrameHeader() muaj nuj nqi tam sim no ua haujlwm ntawm cov ntawv hla dhau ib yam.
- Lwm yam kev txhim kho thiab kho kab mob tau ua.
