F\u00f6retaget Canonical har publicerat resultaten av en utv\u00e4rdering av prestandaf\u00f6r\u00e4ndringar vid omkompilering av paket med aktivering av optimering baserad p\u00e5 profileringsresultat (PGO \u2014 Profilstyrd optimering). Detta g\u00f6r det m\u00f6jligt att generera mer optimerad kod baserat p\u00e5 analys av programmets k\u00f6rningsegenskaper. Under det utf\u00f6rda arbetet kom man fram till att aktivering av PGO-optimering har m\u00f6jliggjort en minskning av CPU-belastningen med 5-7% och en snabbare kompileringstid. <\/p>\n

I den genomf\u00f6rda experimentet m\u00e4ttes prestandan f\u00f6r byggpaketen OpenSSL, GDB, Emacs och Python 3.12 i en virtuell milj\u00f6 med QEMU, som emulerar RISC-V-systemet p\u00e5 en dator med x86_64-arkitektur. Prestandaskillnaden utv\u00e4rderades f\u00f6r QEMU, byggt med standardalternativ och med aktiverad PGO-optimering. De testade paketen valdes med h\u00e4nsyn till att de anv\u00e4nder olika programmeringsspr\u00e5k och att kodvolymen motsvarar 1-6 timmars byggande i emulatorn. <\/p>\n

Fr\u00e5n ett praktiskt perspektiv gjorde experimentet det m\u00f6jligt att \u00f6ka prestandan hos byggmilj\u00f6er f\u00f6r plattformen RISC-V, som k\u00f6rs med en emulator. Byggarbeten som tidigare utf\u00f6rdes p\u00e5 en dag kunde nu genomf\u00f6ras n\u00e4stan tv\u00e5 timmar snabbare med aktiv PGO-optimering, vilket m\u00f6jliggjorde daglig produktion av samma. servern<\/a> tv\u00e5 ytterligare fullst\u00e4ndiga byggnader.
