Linux 3.5 Through Linux 4.4 Kernel Benchmarks: A 19-Way Kernel Showdown Shows Some Regressions

Linux

What better way to spend a cold Friday morning than looking at some kernel benchmarks, so up for your viewing pleasure today are benchmarks of every kernel major release going from the Linux 3.5 kernel up through the latest Linux 4.4 stable kernel release. All the tests were done on the same system and there are actually some interesting performance changes to note with these Linux kernel tests going back to the summer of 2012.

The system I used this week for carrying out this Linux 3.5 to Linux 4.4 kernel comparison was the Xeon E5-2687W v3 Haswell processor (10 cores plus Hyper Threading), MSI X99S SLI PLUS motherboard, 16GB of DDR4 memory, a PNY CS121 120GB solid-state drive, and AMD FirePro V7900 (Cayman) graphics card. All of the hardware was maintained the same throughout testing and each kernel was tested with its defaults as obtained from the Ubuntu Mainline Kernel PPA archive; so you can fetch from there if you are curious about any of the Kconfig and other defaults.

Five reasons to switch from Windows to Linux

Linux has been in the ascendancy ever since the open source operating system was released, and has been improved and refined over time so that a typical distribution is now a polished and complete package comprising virtually everything the user needs, whether for a server or personal system. Much of the web runs on Linux, and a great many smartphones, and numerous other systems, from the Raspberry Pi to the most powerful supercomputers. So is it time to switch from Windows to Linux? Here are five reasons why. Read more

Security Leftovers

  • Chrome vulnerability lets attackers steal movies from streaming services
    A significant security vulnerability in Google technology that is supposed to protect videos streamed via Google Chrome has been discovered by researchers from the Ben-Gurion University of the Negev Cyber Security Research Center (CSRC) in collaboration with a security researcher from Telekom Innovation Laboratories in Berlin, Germany.
  • Large botnet of CCTV devices knock the snot out of jewelry website
    Researchers have encountered a denial-of-service botnet that's made up of more than 25,000 Internet-connected closed circuit TV devices. The researchers with Security firm Sucuri came across the malicious network while defending a small brick-and-mortar jewelry shop against a distributed denial-of-service attack. The unnamed site was choking on an assault that delivered almost 35,000 HTTP requests per second, making it unreachable to legitimate users. When Sucuri used a network addressing and routing system known as Anycast to neutralize the attack, the assailants increased the number of HTTP requests to 50,000 per second.
  • Study finds Password Misuse in Hospitals a Steaming Hot Mess
    Hospitals are pretty hygienic places – except when it comes to passwords, it seems. That’s the conclusion of a recent study by researchers at Dartmouth College, the University of Pennsylvania and USC, which found that efforts to circumvent password protections are “endemic” in healthcare environments and mostly go unnoticed by hospital IT staff. The report describes what can only be described as wholesale abandonment of security best practices at hospitals and other clinical environments – with the bad behavior being driven by necessity rather than malice.
  • Why are hackers increasingly targeting the healthcare industry?
    Cyber-attacks in the healthcare environment are on the rise, with recent research suggesting that critical healthcare systems could be vulnerable to attack. In general, the healthcare industry is proving lucrative for cybercriminals because medical data can be used in multiple ways, for example fraud or identify theft. This personal data often contains information regarding a patient’s medical history, which could be used in targeted spear-phishing attacks.
