Kua kukume te hapori whakawhanake kernel i tētahi miihini VMware Linux ki te hekenga nui o te mahi ina whakamahia te kernel Linux 5.19. I te whakamātautau i tētahi mīhini mariko me te kernel 5.19 i roto i tētahi taiao hypervisor VMware ESXi, i kitea he hekenga 70% o te mahi rorohiko, 30% o ngā mahi whatunga, me te 13% o ngā mahi rokiroki, ki te whakataurite ki te whirihoranga ōrite i runga i te kernel 5.18.
Ko te take o te hekenga o te mahi he panoni i roto i te waehere tiaki Spectre v2 (spectre_v2=ibrs), i whakatinanahia mā te whakamahi i ngā tohutohu Enhanced Indirect Branch Restricted Speculation (IBRS), e āhei ai te whakaaetanga urutau me te whakakore i te whakahaerenga tohutohu whakapae i te wā e tukatuka ana i te aukati, ngā karangatanga pūnaha, me ngā whakawhiti horopaki. Kua whakahohea te tiakitanga hei aukati i te ngoikoretanga Retbleed i kitea tata nei i roto i te tikanga whakahaerenga peka whakapae ā-kore o te CPU, e āhei ai te tango mōhiohio mai i te mahara kernel, te whakaeke rānei i te pūnaha manaaki mai i. mihini marikoI muri i te whakakorenga o te parenga (spectre_v2=off), ka hoki te mahi ki tōna taumata o mua.
