Mau Aplikasi Gacor? Wajib Ngerti Value Type
Mau Aplikasi Gacor? Wajib Ngerti Value Type! (Go vs Java Valhalla)Object yang kita bikin itu disimpan di mana, dan siapa yang bersihin nanti? Kalau jawabannya Heap, Garbage Collector yang harus kerja. Makin banyak object kecil, makin sering GC jalan, makin gampang muncul latency spike.
Di video ini kita bahas cara paling ampuh mengurangi beban GC: bukan tuning GC, tapi TIDAK bikin sampah sejak awal — lewat value type, object yang boleh hidup di Stack dan hilang otomatis tanpa mampir ke Heap.
Go sudah punya ini lewat Escape Analysis. Java lagi menuju ke sana lewat Project Valhalla (JEP 401).
Hasil demo Go-nya, beban kerja identik 10 juta object, cuma beda
"return *Point" vs "return Point"
