V kodno bazo, na osnovi katere se oblikuje jedro Linux 7.0, je bil sprejet niz sprememb, ki so med stresnim testiranjem v 100-gigabitni mre\u017ei omogo\u010dile pove\u010danje zmogljivosti obdelave prihajajo\u010dih UDP paketov za 12%. Optimizacija je bila izvedena z ro\u010dnim inliningom dveh funkcij. Opozarja se, da se funkcija timecounter_cyc2time() lahko kli\u010de ob vsakem prihajajo\u010dem paketu, saj sodobni protokoli zahtevajo upo\u0161tevanje \u010dasa prihoda paketa. Zaradi tega je obremenjena stre\u017enikom<\/a> funkcija timecounter_cyc2time() lahko kli\u010de ve\u010d kot 100 milijonov krat na sekundo. <\/p>\n

V tej situaciji avtomatske optimizacije, ki jih uporablja prevajalnik, kot so FDO (Feedback Directed Optimization), LTO (Link Time Optimization) in PGO (Profile Guided Optimization), niso uspele odkriti vro\u010dega segmenta kode in so ga o\u010ditno prezrle, ker se gonilniki omre\u017enih kartic dobavljajo v obliki lo\u010denih modulov. Vendar je ro\u010dno inline raz\u0161irjanje funkcije prineslo pomembno izbolj\u0161anje zmogljivosti.
