In each setup, two identical systems were used, one for the application server, and the other for the database server. 10 Performance and scalability advantages of the Intel quad core over its single-core architecture. 86 GHz. The total CPU power was the same between the singlecore and quad-core systems. However, the quad-core setup outperformed the single-core setup consistently across all three different types of batch jobs by about a factor of 2, while the cost of each quad-core system was about only half of a single-core system.

Some of the latest Intel Xeon-based systems support both 32-bit and 64-bit operating systems. Xeon processors are intrinsically 32-bit, but can be extended to 40 bits with Intel’s EM64T technology. Therefore, when you have a 64-bit operating system running on a Xeon-based system, the maximum amount of physical memory that can be installed might be limited to 64 GB. Check with the vendor of your system to make sure the exact configurations you have on your system. In the next section, I’ll discuss the service level agreements (SLAs) that have something to do with the other assumption made for the Turing model.
