Going to hold on this update till I see more benches and stability based on Haswell chips, preferably the 5930K which I use.

Nonetheless, thanks EVGA for coming through with an update.

Seems like I can't get that required Windows 10 update either (kb4056892), even when just using Windows Defender as my antivirus.

That would explain it then :)

Anyone else with an NVMe drive got benchmarks?

I was expecting a drop in performance, but not by that much ... Honestly wondering if I did something wrong. That being said, I've triple-checked every setting and it all looks good. Reinstalled drivers, CSM still disabled, along with every other BIOS setting being identical. I fear it's just how it's going to be.

A simple web search shows a bunch of benchmarks being done on various systems and up to 50% disk IO has been lost, NVMe's suffering the most as they hammer the kernel with requests faster. The OS patches that MS released are the cause of your slow downs. These patches are more or less a band aid and the real solution is new hardware with these vulnerabilities fixed that Intel and others in the industry should give away to affected customers. But we all know that would bankrupt the industry.
 
One of the most worrisome benchmarks I seen so far, is from TechSpot. I can not post links so you'll have to do a web search for "meltdown-and-spectre-cpu-performance-windows". I am really hoping that these patches will get refined over the coming weeks/months and that performance will not suffer as much. It is just unacceptable to have your machine suddenly tank in performance to offer some security.
 

Yeh well that's what surprised me, as I say I expected a loss and I know why it's happening, all the benches I'd seen so far were about 30% loss, so my nearly 60% (in the worst case) seems a bit off.

Unless you are doing database or other heavy IOPS work, you won't actually be affected. Games will load just as fast post update.

Yep, I tried manually installing the Delta and the cumulative stand alone patches from that exact webpage last night (the X64 based one ofc). It seems to install fine until the very end, where every single time it fails. That's with and without antivirus installed, and that specific registry key that can prevent the installation set to 0x00000000 as per Microsoft (was already there and set that way).
 
I'm stumped. I manually ran the Windows upgrade assistant to download and install Windows 1709 since i was stuck on 1703 and not getting updates for some reason, and now back to no updates via Windows update even though I'm missing that critical patch form Jan 4.

I don't do a lot of random IO but I do use it sometimes for some light stats work.... but my concern isn't so much that performance drop, it's that the unusually large drop in performance might indicate that I have done something wrong. That's why I was hoping others might have some similar benchmarks so I could see if it's really normal or not.

Regarding your machine, upgrades to windows never seem to work out well, that's a thing that goes way back. It sounds like you might benefit from installing from scratch (read: format the drive, install from USB)

 Hey, my PM961 looks ok i think. Microcode and Windows are updated.
6850k and FTW K

Getting very close to the same as you T_low, no other perf related issues I can see on my rig.
