    Even new scalable line and older cpu ‘can’ be slower, all depends on the products in use , unless you run certain databases or have some specific heavy io patterns likely you won’t notice.

    depends on work loads i.e. ones with alot of system calls will be impacted

    FYI, Phoronix benchmarked KPTI + Retpoline on Ubuntu both Apache and Nginx and saw around 21-26% performance impact for Nginx using apachebench The Combined Impact Of Retpoline + KPTI On Ubuntu Linux - Phoronix.

    I tested Centmin Mod Nginx with Siege bench on i7 4790K on CentOS 7.4 with KPTI only Kernel and got around 5.5% performance impact https://community.centminmod.com/th...nux-kernel-kpti-meltdown-spectre-fixes.13694/

    oh, was the same, only had a brief look as it wouldn't affect me too much.
    But guess evrything io heavy will be affected.

    Is it public knowledge that there is a firmware update for HPE gen9/gen10 hardware (ie E5 v3 onwards) and assume one planned for gen8 (E5 v1/2) but not g7’s

    Has anybody been implementing this along with the software patches for ESX.

    I would be quite interested how much patching will affect fabrics/network performance, both 40GbE and Infiniband.
    I have the bad feeling this could be similar to what happens with IO.
