При поиске инфы по 64-битным процессорам попалась информация о
Sybase ASE под Linux на странице http://www.sybase.com/detail?id=1030009

Заинтересовала фраза

"On Windows, Address Windowing Extensions (AWE)
provide such an API. However, Linux provides a window of virtual address
space that keeps moving over a shared memory file system, allowing 32-bit
applications to address more than 4GB of memory. With ASE 12.5.2,
DBAs can now configure up to 64GB of memory for data caches on
a 32-bit Linux platform .With this feature, customers can now deploy
large enterprise - class databases on the 32-bit Intel/Linux
platform, achieving higher scalability and performance while
maintaining a low TCO, characteristics that have been the hallmark
of Sybase ASE."

Никто не пробовал это в действии ?
