Security patches slow down PCs: Microsoft
Microsoft Corp says software patches released to guard against microchip security threats had slowed down some personal computers and servers, with systems running on older Intel Corp processors seeing a noticeable decrease in performance.
The comments in a blog post were the clearest signal from Microsoft that fixes for flaws in microchips from Intel and rivals described last week could meaningfully degrade performance. The topic is of keen interest to large data centre operators, which could incur significant cost increases if computers slow down.
Microsoft also said that security updates froze some computers using chipsets from Intel rival AMD, dragging AMD's shares down nearly 4 per cent.What the Royals eat on Christmas Day
Security researchers disclosed the flaws that affected nearly every modern computing device containing chips from Intel, AMD and ARM Holdings, owned by Japan's SoftBank Group Corp.
Internet and networking equipment maker Cisco Systems Inc said in a security advisory that it has identified 18 vulnerable products, including some of its blade servers, rack servers and routers, and expects to have patches for servers in about five weeks.
Cisco said it is also looking for problems in nearly 30 other products, including switches and routers. The majority of Cisco's products were not vulnerable because they are "closed systems that do not allow customers to run custom code on the device," it said.Shkreli ex-lawyer convicted in fraud case
Intel and AMD have not disclosed the number of chips affected by the security flaws.
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.
