Remember that: - virtual machines impose a penalty of 1% or more -- worse when not optimally configured - the mitigations for various speculative execution and memory hammer attacks can impose 2-30% penalties depending on specific programs - changes between stable kernel versions can be +/- 15% in some cases All of those can already be cited as "our programmers make mistakes". -dsr- _______________________________________________ Discuss mailing list Discuss@driftwood.blu.org https://driftwood.blu.org/mailman/listinfo/discuss
