Crunching the Numbers: Firefox 4.0 Pulls Ahead

After last week's benchmarking project, I combed through the comments and ran the numbers myself using the latest Firefox 4.0 beta, Chrome 10, and Opera 11. The results? It looks like Firefox 4.0 has the speed crown on Linux, for now.

2.6.38: Making Things Just Work

Linus Torvalds announced the release of the 2.6.38 kernel on March 14. Like its predecessors, 2.6.38 incorporates a lot of work - over 9,500 patches from over 1,100 developers. There are a number of useful changes, including some important scalability improvements, but, in my mind, the most interesting theme behind this kernel is that of making advanced features Just Work. “Pages” are the units of memory as understood by the processor’s memory management unit. Since the beginning, Linux has used 4096-byte pages on most architectures - the smallest size that the MMU understands. Contemporary processors can handle a number of page sizes simultaneously, though, with 2MB or 4MB often being the next largest size available. Larger pages require less overhead to manage, but the real value to their use is that they greatly increase the amount of memory which can be covered by the processor’s translation lookaside buffer (TLB). The TLB, which caches virtual-to-physical address translations, is a severely limited resource on most systems. But it is important; a TLB miss can cost many hundreds of processor cycles even if the destination page is fully resident in memory. A 2MB page requires one TLB entry; the same memory, in 4096-byte pages, needs 512 TLB entries. So using huge pages can save a lot of TLB misses, leading to significant performance increases, especially in virtualized situations. Linux has supported the use of huge pages for years, but...

Open Compliance Focus for April is on Collaboration

Here at The Linux Foundation, we’re preparing for next month’s Collaboration Summit, where we’re going to have a number of sessions dedicated to Open Compliance. We are hosting a FOSS Compliance track with talks reflecting the current state of compliance and new resources just over the horizon. We’re also hosting SPDX working sessions that will work on key technical and business issues prior to release of version 1.0 of the SPDX spec. In parallel, our Director of Technology & Alliances, Ibrahim Haddad, will be participating at the IP Counsel Café April 7 at the Sheraton Palo Alto.  We hope some of you can join us south of the city that day to hear Ibrahim discuss Open Compliance with co-panelists Alyssa Harvey, Associate General Counsel at Netflix, and Diane Honda, Vice President, General Counsel & Secretary of Extreme Networks. The three of them will be discussing the legal side of open source software and open source compliance programs.  I know Ibrahim is planning to discuss the practical steps involved in building a corporate compliance program to manage the consumption of...
