Attention to: Microsoft Expert
My computer setting is Dual-XEON 2.66, 1GB RAM with
Windows XP Professional. Hyper-Threading Technology is
enabled, therefore, I am able to see four logical
Processors. However, when I open single Excel 2000
spreadsheet for calculation, it consumes 25% of CPU and
130MB RAM on computing resources. If I disable Hyper-
Threading Technology, then it displays only 2 CPU
processors only, and I try to run the same single Excel
2000 spreadsheet for calculation, it consumes 50% of CPU,
of course, the speed of calculation is faster. Could you
tell me why Hyper-Threading Technology cause 25% CPU
consumption rather than 50% CPU consumption? Is Excel 2000
multithreaded Windows applications? It seems to me that
Single Excel 2000 spreadsheet runs faster without Hyper-
Threading Technology. However, there is still other 50%
CPU rsource leave unused, until I run another additional
Excel 2000 spreadsheet, which I totally run 2 Excel's
spreadsheet, it consumes around 95% CPU consumption.
Could you please give me any suggestion on how to run only
single Excel's spreadsheet with usage of CPU consumption
above 90% to improve the calculating performance.

I look forward to your reply.
