Enhancements have been made to the internal performance that concern 64-bit operating systems and operating system thread implementation on Linux.
Now that Microsoft, Sun, HP, and Linux vendors have produced 64-bit versions of their operating systems, we are providing a 64-bit build of Ingres on these platforms. Every effort is made to exploit large memory and files in these 64-bit environments.
Ingres 2.6 provides support for operating system threads in Linux environments including Intel, Alpha, S/390, and IA64. Operating system threads perform better in most circumstances than the internal Ingres threading model.
