Windows Performance Impact Of Meltdown And Spectre

By

Microsoft exec Terry Myerson lays out what he expects the performance impact of the Meltdown/Spectre patches.
– With Windows 10 on newer silicon (2016-era PCs with Skylake, Kabylake or newer CPU), benchmarks show single-digit slowdowns, but we don’t expect most users to notice a change because these percentages are reflected in milliseconds.
TH – Skylake released 2015. Kaby Lake 2016.
– With Windows 10 on older silicon (2015-era PCs with Haswell or older CPU), some benchmarks show more significant slowdowns, and we expect that some users will notice a decrease in system performance.
TH – Haswell released 2013.
– With Windows 8 and Windows 7 on older silicon (2015-era PCs with Haswell or older CPU), we expect most users to notice a decrease in system performance.
TH – Haswell released 2013
– Windows Server on any silicon, especially in any IO-intensive application, shows a more significant performance impact when you enable the mitigations to isolate untrusted code within a Windows Server instance. This is why you want to be careful to evaluate the risk of untrusted code for each Windows Server instance, and balance the security versus performance tradeoff for your environment.
TH – You’re attached to another object by an incline plane wrapped helically around an axis.

Conveniently left out is any reference to Microsoft bricking AMD machines.
I will repeat my advice to not update Windows machines right now. Certainly you need to have a full image backup before you do.
I recommend Macrium Reflect 7 Free Edition.

To find your CPU family.
Those odd names are CPU Family or CPU Code Names (Haswell, Skylake, Kabylake…).
Download Speccy PORTABLE and run it.
Click the CPU tab. Find the line Code Name, that is your CPU family.
Google it or, see: https://en.wikipedia.org/wiki/List_of_Intel_microprocessors

My Home Server – Windows 7

By

Here is my current setup. I will be attempting to switch over to a Linux server setup in the near future (just because).
This machine was my secondary workstation and has been repurposed for my home server.
This is a quickie article. No hand holding. If you do not know your way around Windows this article is not for you.

Profound Post

By

I don’t post in forums much. I don’t comment in posts much either. I may scan through comments on non-political type posts. There are a few places where most comments are level headed. Askwoody.com Forums is one such place. Once in a while a comment truly impresses me.
A comment by user Canadian Tech is an example. I’ve no idea who he is. I don’t necessarily agree with everything he said but his argument is solid, well reasoned, and well written. If he isn’t a tech writer he should be.

Get Rid Of SMB1 In Windows 7

By

A reader was confused by all the steps in Microsoft’s How to enable and disable SMBv1, SMBv2, and SMBv3 in Windows and Windows Server.
Should he use PowerShell, Registry Editor, Group Policy? Should he disable it on Client or Server or both?
Because it is a security risk, it is important to ditch SMB1 on all platforms.
You should get rid of both the client and server.
In Windows 7 I do this via PowerShell. It is fast and easy.
You must run PowerShell as Admin.

Press the Windows + R keys > type powershell (press the Enter key)
> copy and paste the following command:
Set-ItemProperty -Path “HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters” SMB1 -Type DWORD -Value 0 -Force
> now press the Enter key
> copy and paste the following command: sc.exe config lanmanworkstation depend= bowser/mrxsmb20/nsi
> now press the Enter key
> copy and paste the following command: sc.exe config mrxsmb10 start= disabled
> now press the Enter key > Reboot

Best to follow his advice.

Linux Swap Partition
Red Hat Blog – Do we really need swap on modern systems?
“How much swap is recommended nowadays?
This depends on the desired behaviour of the system, but configuring an amount of 20% of the RAM as swap is usually a good idea. More details are in this solution document.
Can I run without swap? Is further tuning possible?
Systems without swap can make sense and are supported by Red Hat – just be sure the behaviour of such a system under memory pressure is what you want. In most environments, a bit of swap makes sense.”

Cleaning Up The Script

By

In my post Blocking Windows 7 Telemetry I provided a script to remove Windows 7 telemetry updates. This was done in haste from an older script and I have now cleaned it up.
One poster in the AskWoody lounge stated certain updates were no longer there. I asked him to provide some documentation so I could verify his statement and he did not.
So, I had to dig in and find the answer myself. I checked a few of the KB articles for the updates and there weren’t any notices about updates being removed or superseded. That is par for the course for Microsoft.
