How to Check and Update Windows Systems for the Meltdown and Spectre CPU Flawshttps://www.bleepingcomputer.com/news/microsoft/how-to-check-and-update-windows-systems-for-the-meltdown-and-spectre-cpu-flaws/
My entire work world lives on encrypted data, virtual machines, and various VPN tunnels. I use VMs because I run VPNs from my desktop and RDP to remote hosts. That way I can do my remote work securely while still having access to the internet on my desktop.I also run my entire data drive through TrueCrypt at the partition level. I don't use it for my OS drive which is physically separate. I'm keeping my eyes out for a big performance hit.How I think this might play out pragmatically is that we could feel a cumulative performance hit. I don't expect my VM to suddenly become slower. I expect the VM, and VPN, and the entire virtualized host network to all contribute small pieces to performance degradation. I'm not entirely sure we'll even feel that in real time interaction. I think we'll see that in longer processing times that add up to larger loss of productivity.I expect to see this in my ETL (extract, transform, load) jobs between databases or in file conversions. For example, say I have to move 100k patients between systems with 500GB of discrete data and it used to take me 20 hours. If that now takes me 26 hours of processing time, that can balloon into a couple more days of people time which adds a huge amount of cost or loss to my productivity and our revenue.It's even worse I fear with file conversions. I do a lot of those between systems. Medical people scan a lot and create a lot of documents and they often want them converted to formats for a new system or packaged into a single PDF. Converting 10 million files and moving them to a new location can take weeks depending on hardware. Even a 5% across the board increase is going to be incredibly painful. I'm hoping in this situation that I/O is still the main bottleneck.I'm also curious how this will affect performance for interpreted languages. Java, .NET, and Python all use an interpreter which is essentially a virtualization layer that interprets byte code to binary. We use those heavily and most of our third party tools are written in Java and .NET.Like Quizz said this is actually a set of issues and there is a lot to chew on and unpackage. I'm not worried about security or my personal information on Amazon so much as how this will affect the tech landscape productivity.
Intel has released an update addressing the patches the company has issued to resolve recently-revealed, massive CPU security flaws, and the performance hits (and other quirks) users are experiencing in the wake of the updates. The "Meltdown" and "Spectre" errors opened the door to exploits that allow an attacker to swipe data from a PC running millions of CPUs made since the mid-nineties.
The scope of the flaw was monumental, though the affair was compounded by security updates that have impacted performance and system stability.
Not only are users who applied these updates now facing notable performance degradation of their CPUs, some customers are seeing constant reboots in the wake of Intel's solution to the problem, something Intel addressed in its blog post.
"We have received reports from a few customers of higher system reboots after applying firmware updates," Intel states. "Specifically, these systems are running Intel Broadwell and Haswell CPUs for both client and data center. We are working quickly with these customers to understand, diagnose and address this reboot issue."
Intel's post came on the heels of a Wall Street Journal story claiming that Intel is teling some customers to delay applying the update to avoid system stability problems. That report cited an internal Intel document disclosing that the company identified three issues in microcode updates released over the past week intended to address the vulnerabilities. The warnings were shared with computer makers and large cloud providers, but not consumers or smaller companies.
Another Intel update clarifies just what kind of a performance hit impacted users are seeing on their systems after applying updates.
According to Intel, computers equipped with 8th generation (Kaby Lake, Coffee Lake) chips and sold-state-drives (SSDs) will see the least slowdown from the Spectrum/Meltdown update at less than 6%. Devices using the 7th Gen Kaby Lake-H mobile processors will be around 7% slower, while the performance impact on systems with the 6th Gen Skylake-S platform is estimated to be around 8%. Needless to say, enterprise users and hobbyists alike are immensely frustrated by having to choose between system security and system stability and performance, and that Intel isn't being fully forthright with some customers.
"As we collect more information across the broad range of usages and Intel platforms, we will make it available," Intel says of the slowdowns and rebooting issues. "Within the next week, we intend to offer a representative set of data for mobile and desktop platforms that were launched within the past five years. For those Intel customers who are worried about performance impacts, you should know that we will work on creative solutions with our industry partners to reduce those performance impacts wherever possible."
