I dont think that xeons have advantages over file managment
The Xeon brand refers to many families of Intel's x86 multiprocessing CPUs - for dual-processor (DP) and multi-processor (MP) configuration on a single motherboard targeted at non-consumer markets of server and workstation computers, and also at blade servers and embedded systems. The Xeon brand has been maintained over several generations of x86 and x86-64 processors. Older models added the Xeon moniker to the end of the name of their corresponding desktop processor, but more recent models used the name Xeon on its own. The Xeon CPUs generally have more cache than their desktop counterparts in addition to multiprocessing capabilities. Intel's (non-x86) IA-64 processors are called Itanium, not Xeon.
The 3000 series, codenamed Conroe (product code 80557) dual-core Xeon (branded) CPU, released at the end of September 2006, was just rebranded version of the Intel's mainstream Conroe otherwise branded as Core 2 Duo (for consumer desktops). Unlike most Xeon processors, they only support single-CPU operation. They use Socket T (LGA775), operate on a 1066 MHz front-side bus, and do not support Hyper-Threading. Processors with a number ending in "5" have a 1333 MT/s FSB.
