general question on speed using quad core Xeons

[Barry Smith]

    Cool. The pages to look at are

http://www.intel.com/performance/server/xeon/hpc_ansys.htm
http://www.intel.com/performance/server/xeon/hpc_md_nastr.htm

these are the two benchmarks that reflect the bottlenecks of memory  
bandwidth.
When going from dual to quad they get 1.2 times the performance, when  
one would
like 2 times the performance.
