The Quintessential Linux Benchmark

When Linux boots, it displays a “BogoMips” number. What does that mean? Is the number displayed correct? What use is the infromation? This quintessential part of Linux is demystified in this article.
Complete Reference Table: BogoMips Mini-HOWTO

The BogoMips mini-HOWTO gives a full table of reported BogoMips for various systems. More than 250 BogoMips references as reported on Usenet, or sent directly by e-mail to the maintainer, are listed with information about CPU type, clock speed, BogoMips, and the name and e-mail address of the reporter. For example, the lowest and highest BogoMips reported in the current version of The BogoMips Mini-HOWTO are:

The Lowest: H. Peter Anwin pa@nwu.edu 386SX/16 387 nocache 0.57 BogoMips The Highest: David Mosberger-Tang davidm@cs.arizona.edu Alpha 21064A/275 273.37 BogoMips

In the BogoMips mini-HOWTO, values that do and do not comply with the aforementioned BogoMips calculation methods are listed. The non-complying group is named “Oddly or Faultily configured” because non-compliance does not necessarily mean that the system is faultily configured.

Benchmarking

The BogoMips may be used to see whether your system is faster than mine. Of course this is completely wrong, unreliable, ill-founded, and utterly useless, but all benchmarks suffer from this problem, so why not use it? This inherent stupidity has never before stopped people from using benchmarks, has it? [Note for the humor-challenged: no angry letters to the editor will be accepted on this point. —Ed]

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
