What Do Microsoft's Spectre And Meltdown Fixes Do To Performance?

Microsoft has identified a compatibility issue with a small number of antivirus software products.

If you have run into this issue and can get back into the OS, a little RegEdit wizardry can help you out so that you can move forward and get those security updates.

The Meltdown and Spectre CPU vulnerabilities affecting millions of machines around the world are now being tackled.

The performance impacts are felt more significantly in older operating systems because Windows requires more user-kernel transitions to accommodate legacy design decisions, such as all font rendering taking place in the kernel, Myerson wrote.

On the other hand, Windows 7 and 8 PCs with the processors like Haswell will notice a significant decrease in system performance.

The question many will be asking is whether the performance hit is a price with paying for the security mitigation. In general, our experience is that Variant 1 and Variant 3 mitigations have minimal performance impact, while Variant 2 remediation, including OS and microcode, has a performance impact.

Currently, Microsoft supports 45 different releases of Windows.

This means that users who suffer from the patch issue will therefore need to disable Windows Update, as their only option.

As expected, the patch for found vulnerabilities might slow down some old PCs and impact on performance could be significant. "Windows operating system updates to devices with impacted AMD processors at this time".

Security researchers disclosed the flaws on January 3 that affected almost every modern computing device containing chips from Intel, AMD and ARM Holdings, owned by Japan's SoftBank Group Corp. However, users of older Windows 10 systems, namely "2015-era PCs with Haswell or older CPUs", will likely perceive a system slowdown.

Intel said a typical home and business PC user should not see significant slowdowns in common tasks such as reading email, writing a document or accessing digital photos. The company has provided a reasonably detailed description of the impact.

Microsoft Corp said on Tuesday that software patches released to guard against microchip security threats slowed down some personal computers and servers, with systems running on older Intel Corp processors seeing a noticeable decrease in performance.

Intel said its processors would be affected based on the type of operations the CPU would carry out, saying that syscall-heavy processes would suffer the most.
