[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...

So far many pipers from the BW family like the tunes.
I think composing is a very vain process... not sure if a lot of people are willing to bend an ear to my take of Highland pipe music. I think it arrogant to impose upon the band that I play in to play my tunes. But anyhow, a few people say from time to time that "we should play" one of my tunes, and that notion is always a very kind compliment.
Haven't been checking my PO Box much lately, but if you have ordered one let me know so I can get a package ready for you! Cheers Glen
