La riduzione dei tempi di linking consente di migliorare notevolmente la comodit\u00e0 nello sviluppo di grandi progetti, riducendo i tempi di attesa durante la creazione dei file eseguibili durante il debug e il test delle modifiche. La motivazione alla base della creazione di Mold \u00e8 stata la frustrazione per la necessit\u00e0 di attendere il completamento del linking dopo ogni modifica al codice, oltre alla bassa efficienza dei linker esistenti sui sistemi multicore e il desiderio di provare un'architettura di linking fondamentalmente diversa, senza ricorrere a modelli eccessivamente complessi come il linking incrementale. <\/p>\n

Le elevate prestazioni della creazione del file eseguibile da un gran numero di file oggetto preparati dal compilatore in Mold si ottengono utilizzando algoritmi pi\u00f9 veloci, parallelizzando attivamente le operazioni tra i core CPU disponibili e applicando strutture dati pi\u00f9 efficienti. Ad esempio, in Mold \u00e8 implementata una tecnica per eseguire calcoli intensivi simultaneamente alla copia dei file, il caricamento anticipato dei file oggetto in memoria, l'uso di tabelle hash veloci per la risoluzione dei simboli, la scansione delle tabelle di spostamento in un thread separato e la deduplicazione delle sezioni duplicate in diversi file.
