Also note that the OS has a lot to do with it. Hyperthreading was
making my compiles and run twice as fast on Win2k. But on XP, it is
slower. This is on exactly the same hardware.
Peter, this thread started as I found that in our apps (running on XP)
the gui update of 300 edit boxes took about 10 times longer when the
task manager showed the cpus loaded evenly as compared to only one cpu
loaded. Nothing else was running, it was the whim of the XP as what it
ran on which cpu. It still makes no sense to me. Does this mean that
for several years now the users of our apps have been living with what
they thought was a slow app ?

Thats the original blog I quoted, from an MS SQL team member, which
includes his tests and results regarding how to make Hyperthreading
perform badly..
