Java, MySql increased performance with Huge Pages

[Resources updates: 2010.07.07 , 2009.11.03 , 2009.05.27 ] Long running, large memory, high performant applications often have special needs with respect to their memory management. On Linux, Solaris and other modern OSes, the translation look-aside buffer ( TLB ) - whose page size of 4k for many CPUs/OSes - becomes a scalability issue in these extreme conditions. In order to get around TLB scalability issues, huge page sizes are used to reduce the impact on performance. This can be of use to installations with large scale Java, MySql and other large memory applications. 300% improvement : " Well, in my case, I was able to achieve an over 3x improvement in my EJB 3 application, of which fully 60 to 70% of that was due to using large page memory with a 3.5GB heap. Now, a 3.5GB heap without the large memory pages didn't provide any benefit over smaller heaps without large pages. Besides the throughput improvements, I also noticed that GC frequency was cut down by two-third

IBM on Linux: "Lean, clean, and green"

IBM developerWorks has an article ( Linux: Lean, clean, and green: How GNU/Linux is becoming more eco-friendly - 26 May 2009) which examines some of the Green benefits of the Linux operating system. It focuses primarily on the low resource demands Linux has on systems (as well as its support for older systems), thus extending the life of machines that would otherwise be junked. Also discussed is virtualization and aspects of the Linux OS that reduce power consumption in servers.

Mars Inc. Cacao Genome Database claims Open Access, public domain: falls short

This initially looked very promising: Mars , along with a number of collaborators (USDA, IBM, Clemson University Genomics Institute; Public Intellectual Property Resource for Agriculture at the University of California-Davis; National Center for Genome Resources; Center for Genomics and Bioinformatics at Indiana University; HudsonAlpha Institute for Biotechnology; and Washington State University), have sequenced the cacao genome and released it "Open Access" and "public domain" for the benefit of all, at a site called the Cacao Genome Project : McLean, VA –Today, Mars, Incorporated, the U.S. Department of Agriculture-Agricultural Research Service (USDA-ARS), and IBM released the preliminary findings of their breakthrough cacao genome sequence and made it available in the public domain . - From the Mars Inc. press release 15 September 2010 A quote from the Independent article on the release ( First rice, then wheat – now cocoa genome unravelled 15 Sep 2010) f
