As I understand hyperthreading, this is not true: >Also, unless you take your hyperthreading off, with just one index you are >searching with just one half of the CPU - so your desktop is actually using >a 1.5GHz CPU for the search. You still have the full speed of the processor available - the processor itself just keeps switching between different threads of execution. Some people have noted that some (single threaded) applications will run 5-10% slower when hyperthreading is turned on - but that depends on the app. It certainly won't be running at half speed.
