Performance regression in linux kernel 5.19 – after performing the bisect between kernel 5.18 and 5.19 we identified the root cause to be the enablement of IBRS mitigation for spectre_v2 vulnerability by commit 6ad0ad2bf8a6 („x86/bugs: Report Intel retbleed vulnerability“) to confirm this we have disabled the above security mitigation through kernel boot parameter(spectre_v2=off) in 5.19 and re-ran our tests and confirmed that the performance was on-par with 5.18 release
