Yes Fernando, I agree totally.

@100pier

Well I very appreciate the feedback.

Thanks for taking the time to share those results.

On a P8Z77-V Deluxe platform ENABLING Meltdown/Spectre protection does heavily impact the performances even when booting.

1) For instance, after booting the negative impact for any typical System Backup Applications (Acronis, AOMEI, Paragon) is minimum 13 %
For pure big File transfer the negative impact is huge: 54 %

2) The boot time also is negatively impacted as measured here (18%) below:
Protection ENABLED: Protection DISABLED:

F that. Unless you are worried about security I don’t see any reason to have these patches enabled on older machines. We should open up a poll and see how many people have this turned on. I bet in the coming months we are going to see a lot of rollbacks. I for one had to get a faster SSD drive because of the slow down in my laptop. Feels better and more responsive for Sata 3 6G interface. If only it had Nvme support.

@davidm71:
If your laptop has a mini PCIe slot then you should be able to use an M.2 to mini PCIe adapter for NVMe. Mini PCIe splitters also exist that might be used for keeping the WiFi card too, depending on motherboard support.

@ethaniel,

Thats interesting. I'm not sure about if it has a mini pcie slot or not. Its a Dell XPS 13 9343 and if the wifi is routed through a mini pcie slot i would probably loose wifi if it cant be split. Furthermore would have to mod the Dell bios for nvme support which employs Bootguard. Tricky to flash and not brick. Maybe next year worth looking into. Thanks.

InSpectre v8.0 Tool is now available.
Apparently with v7.0 my system was fully protected, and with this new version my system is no longer SPECTRE prrotected.

@Fernando
On your side do you observe any different InSpectre diagnostic Tool between Release #7 and Release #8 ?
I don't understand why SPECTRE Protection was OK with Release #7 and now Release #8 said notOK !
I do observe also new Ashampoo SpectreMeltdownCheck v1.1.2.1 (1304) does confirm the Inspectre Release #8 diagnostic.

I do use the same BIOS with µC=1C for the both tests, the only difference is the last MS W10 x64 Patch Tuesday applied (build 16299.371).

my old xeon is normal performance

What W10 x64 exact version do you have ?

3930K on x79 sabertooth, win8.1, with the new microcode the performance hurt is huge which force me to disable the patch. I also can see many micro stuttering in chrome with html5.

100PIER, could you please explain the details of your P8Z77-V system, i.e. OS, SSD?

I guess the most performance penalty is caused by the microcode update (Spectre patch), since I have an ivy bridge system with a single meltdown fix installed and can see only 0-3% speed loss in AS SSD and Anvil.

This is good video for people who don't know anything about the subject.

It is Windows 10 glitch. I was same issues after System recovery few day back.

My solution to fix this problem:
manually re-install latest spectre KB4090007
enable protection via registry keys (FeatureSettingsOverride, FeatureSettingsOverrideMask)
