Better CPU Utilizaton in Teamed Environment

Provides lower CPU utilization than TOE in teamed interfaces.

Relative performance for each benchmark is calculated by taking the actual benchmark result for the first platform tested and assigning it a

value of 1.0 as a baseline. Relative performance for the remaining platforms tested was calculated by dividing the actual benchmark result for

the baseline platform into each of the specific benchmark results of each of the other platforms and assigning them a relative performance number

that correlates with the performance improvements reported. Performance tests and ratings are measured using specific computer systems and/or

components and reflect the approximate performance of Intel® products as measured by those tests. Any difference in system hardware or soft-

ware design or configuration may affect actual performance. Buyers should consult other sources of information to evaluate the performance of

systems or components they are considering purchasing. For more information on performance tests and on the performance of Intel products,

reference http://www.intel.com/performance/resources/benchmark_limitations.htm or call (U.S.) 1-800-628-8686 or 1-916-356-3104.

Intel® I/O Acceleration Technology (Intel® I/OAT) requires an operating system that supports Intel I/OAT.

Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across

different processor families. See http://www.intel.com/products/processor_number for details.
