Server Features
Hyper-Threading technology, developed by Intel, improves the performance of IA-32
processors when executing multiple-processor (MP) capable operating systems and
multithreaded applications. With this technology, one physical processor looks like
two logical processors to the operating system and applications. The two logical
processors can execute two separate tasks (or code streams called
threads
)
concurrently by using shared hardware resources.
Hyper-Threading technology is designed to improve the performance of IA-32
processors by using the multithreaded nature of contemporary operating systems and
server applications in such a way as to increase the use of the on-chip execution
resources available in the Intel NetBurst microarchitecture. The integrated cache
subsystem results in reduced memory access times and increased throughput and
performance of the memory subsystem. Specifically, integrated Level 3 cache, which
is only available on the Xeon processor MP, provides a high-bandwidth path to
memory, increasing throughput for large server workloads.
