Excel still slow with SP2, despite claims of improved charting.

I have high hopes for performance improvements each time MSFT releases an new version or service pack.  This time the claim with Office 2007 service pack 2 that had me curious was:

Improves the charting mechanism in Excel 2007. This includes better parity with Office 2003, improved robustness, and targeted performance improvement”

Benchmark.xls is a file I created to keep track of Excel’s performance in various O/S and versions. Benchmark.xls makes heavy use of Excel’s charting capabilities and manipulates data in a way typical for handling live market data/trading.

With SP2, Excel still took roughly two and a half hours to complete what takes Office 2003 five minutes.
