Google says its security patches not slowing down systems

He says that users should continue to apply any updates that are made available for their systems. For example, all fonts in Windows 7 and 8 are rendered on the kernel, the software that controls the processor. They also said that the impacts are "workload-dependent", and pointed out that other processors are affected by Meltdown and Spectre, as well.

The statement continued: "AMD will make optional microcode updates available to our customers and partners for Ryzen and EPYC processors starting this week".

The world's largest chipmaker confirmed last week that the security issues reported by researchers in the company's widely used microprocessors could allow hackers to steal sensitive information from computers, phones and other electronic devices.

The flaws affect virtually all computing devices running on chips manufactured by Intel, AMD and ARM, although the worst - called Meltdown - largely just affects Intel. Later in December, Google issued another patch for Variant 2 of Spectre, which Google said was more difficult to fix without slowing systems down. Nvidia said that its initial analysis concluded that updating the second Spectre variant (CVE-2017-5715) will require more investigation.

Three firmware issues have been flagged by the company in updates released over the past week, according to a confidential document reviewed by The Wall Street Journal. "The topic is of keen interest to large data-center operators, which could incur significant cost increases if computers slow down". Presumably, it would take too much work to fix operating systems that are supposed to be discontinued in a few years anyway.

The public disclosure on January 3rd that multiple research teams had discovered security issues related to how modern microprocessors handle speculative execution has brought to the forefront the constant vigilance needed to protect and secure data.

Lastly, the Intel CEO reaffirms the company's broader committment to user security, calling it an "ongoing priority, not a one-time event".

But even more concerning was Microsoft warning that Windows Server instances will have a "more significant performance impact", especially if servers are I/O intensive.

The slowdown particularly affects Intel chips vulnerable to Meltdown.

Intel has fought the idea that patching the flaws will cause major slowdowns on the systems its chips are running.
