Patch KB4056892 aftermath

Nah Xirok · January 6, 2018

Not really a problem to solve, just thought I'd post some info here.

I believe this patch was in response to the Meltdown and Spectre vulnerabilities. And after see some disk benchmarks online I decided to do my own. In the picture, #1 had run pre-patch using the automated 'all' button. #2 is post-patch again using the 'all' button. In #3, I ran each test type separately with 2 minutes or more in between starting each. In all 3 cases the results were repeatable and consistent. You can see my sig for hardware setup.

When comparing 2 & 3, take note of Q8T8 & Q1T1 Reads. When comparing 1 to 2/3, also note the 4K Q32T1 & Q1T1 writes along with the previously mentioned tests.

Aside from disk performance I will also note that my antivirus (symantec endpoint) is throwing warnings but still functioning. AI Suite 3 went on strike but Asus had a beta version already on their forums. And Aura lighting software has a mini stroke for like 5 mins when I first turn on my computer where its unresponsive (using 2% of my 1700's cpu continually during) then returns to normal.

EDIT: I will also mention that other than this I haven't noticed anything else yet performance wise in my use case.

960 Evo loses but 850 Evo and Optane gain speed.

So far there's something weird going on with the 960 Evo.

I did notice a large spike in my 850 Pro benchmarks through the Samsung Magician software. But I do have RAPID Mode enabled on it, which can be wonky on benchmarks by itself, and I also don't trust the Magician benchmarks. I don't remember the exact numbers but I'm pretty sure it was around 3GB/s for both read and write before.
