Nokho, lezi zinzuzo ziza ngezindleko zesikhathi eside sokuhlanganiswa. Kufanele ukhethe nini ukuhlanganisa amaphasi amaningi? Uma usebenza kuphrojekthi lapho ukusebenza kwekhodi ehlanganisiwe kubaluleke kakhulu, njengamasistimu ashumekiwe noma izinhlelo zokusebenza ezisebenza kahle kakhulu, lolu hlobo lomdidiyeli lungaba umsizi wakho ongcono kakhulu.
Abahlanganisi be-JIT (Just-In-Time): Inguquko yokuhlanganisa enamandla
Abahlanganisi be-Just-in-time (JIT) bashintshe indlela esicabanga ngayo ngokuhlanganiswa. Yini eyenza bakhetheke kangaka? Laba bahlanganisi bahumusha ikhodi ibe ulimi lomshini ngesikhathi sokusebenza, ngesikhathi esifanele.
Ezinye izinzuzo zabahlanganisi be-JIT yilezi:
- Ukuthuthukisa ngamandla okusekelwe ekuziphatheni kwangempela kohlelo
- Ukusebenza okungcono ezinhlelweni ezisebenza isikhathi eside
- Ikhono lokuzivumelanisa nezakhiwo ezahlukene zehadiwe
I-Java ne-.NET ziyizibonelo ezivelele zamaplathifomu ezisebenzisa ukuhlanganiswa kwe-JIT. Ingabe lokhu kusho ukuthi ukuhlanganiswa kwe-JIT kuhlale kuyinketho engcono kakhulu? Akunjalo. Kuzinhlelo zokusebenza ezidinga ukuqalisa ngokushesha noma ezinesikhathi esifushane, isihloko esiphezulu sokuqala sokuhlanganiswa kwe-JIT singase singathethelelwa.
Abahlanganisi abakhuphukayo: Ukwenza lula umjikelezo wokuthuthukisa
Ama-compilers angeziwe ayisisombululo esihlakaniphile senselele yokuhlanganisa amaphrojekthi amakhulu. Asebenza kanjani? Esikhundleni sokuhlanganisa kabusha yonke ikhodi njalo lapho kwenziwa ushintsho, ahlanganisa kabusha izingxenye ezishintshiwe kuphela.
Izinzuzo ezibalulekile zabahlanganisi abakhulayo:
- Izikhathi zokuhlanganisa zehliswe ngokuphawulekayo
- Impendulo esheshayo yonjiniyela
- Ukuhlanganiswa okungcono nezindawo zokuthuthukisa ezisebenzisanayo
Ukugqwala kuyisibonelo solimi olusebenzisa kakhulu ukuhlanganiswa okukhulayo. Ingabe kufanele ucabangele ukuhlanganisa okungeziwe kwephrojekthi yakho elandelayo? Uma usebenza kuphrojekthi enkulu enokwakhiwa njalo, lokhu kufanelekile ukucatshangelwa.
