Ettev\u00f5te Canonical avaldas tulemused koodiprofiilide p\u00f5hjal t\u00f5hususe hindamisest pakettide uuesti koostamisel, mis h\u00f5lmab Profiloitud Optimiseerimise (PGO) kasutamist.

T\u00f6\u00f6 k\u00e4igus j\u00e4reldati, et PGO optimiseerimise rakendamine v\u00e4hendas CPU koormust 5-7% ja kiirendas koostamisprotsessi. <\/p>\n

J\u00f5udluse erinevust hinnati QEMU puhul, mis oli kokku pandud vaikeseadete valikutega ja PGO optimeerimisega. Testimiseks valiti pakettide ehitamiseks erinevaid programmeerimiskeeli, mille kood maht vastab 1-6 tunni ehitusele emulaatoris. <\/p>\n

Praktiliselt v\u00f5imaldas eksperiment parandada RISC-V platvormide ehituskeskkondade j\u00f5udlust, mis t\u00f6\u00f6tavad emulaatori abil.
