Why does adding columns slow down processing speed?
I have a workbook (using Excel 2002) that takes the data on the worksheet
"AllDealers" (960 rows x 112 cols) and spreads it to regional sheets (16 in all). This process (on my machine usually takes about 4-6 minutes. Then I added another 91 columns with historical data and now the same calculation takes approximately 1 hour and 15 minutes. What a difference? Can anyone explain why? If I were to put this historical data in another worksheet, how can I tie the two sheet together? Any help will be appreciated. |

Difficult to say without any formulas.

Why does adding columns slow down processing speed?
Each row has information for an auto dealer such as current monthly volume,
outstandings, etc along with the region (territory) where the dealer does business. Each month I update the info in each row and then have to allocate (spread) that dealers information to a worksheet for that particular region, so my managers can see only their volumne, outstandings, etc. "Niek Otten" wrote: Difficult to say without any formulas.

Why does adding columns slow down processing speed?
Not sure what formulas you are referring to? I build (allocate) region
worksheets from the data on the Master worksheet using VBA. When the master worksheet had 112 columns of data and I only copy the first 24 columns to the region sheets the process runs in 4-8 minutes. Then I added another 91 columns of historical data to be used in calculating a risk rating for the dealer, but I still only copy the first 24 columns the process takes 94 minutes. Why?

Hi
Maybe if you use Application.EnableEvents = False Application.Calculation = xlCalculationManual .. .. (your code for doing your copying etc.) .. Application.Calculation = xlCalculationAutomatic Application.EnableEvents = True -- Regards Roger Govier "Cheer-Phil-ly" wrote in message ... Not sure what formulas you are referring to?
