xp/2003 vs vista/2007
i am just curious if anyone sees a substantial degradation of speed when using
vistax64/2007 vs xp/2003. i was on the beta for both vista and office 2007, and refuse to use either. i dual boot. when i run an app under vistax64/2007, it takes 4 seconds to complete, while under xp/2003 it's maybe a second. i know it doesn't seem like much, but everything i run is slower. this particular app loads and closes about 10 workbooks while it populates a schedule and does some other things. i personally think they're both useless and i'm glad i got them for free. someday when i feel like punishing myself, i'll install my 32 bit version of vista and see if it's any better. -- Gary |

Office efficiency mostly depends on video driver perfomance (to test, you need to disable screen update in your macro) - I test Offices from 97 to 2007 on Core 2 Duo 6300 with 2Gb RAM (you must have at least 2Gb to archieve same memory space conditions in XP and Vista, otherwise, you can compensate it with multiply reloads of Office application you test, to assure, that it completely cashed in RAM) and windows from 98SE(Support only 768Mb RAM and old Offices) to Vista. Results depend only on Video subsystem (used onboard, PCI, PCI-E), or, on Driver performance (tested on PCI-E GeForce6800 with different ForceWare versions). Win98 gives worse results, than other systems - it has no full video hardware acceleration support (I used system with AMDs X2 and Athlon, both based on Manchester core to test dependense on CPU number). Win2000's result is best, and I bet, due well optimised drivers (almost all issues fixed, after a long time). Vista shows best multiple CPU support (for macro, that creates word report and PowerPoint poster,based on external application data, sent to Excel) |

xp/2003 vs vista/2007
I ran a test of doing a monte carlo simulation with 2003 and 2007. 10,000
simulations in 2003 took 5 minutes. In Excel 2007, it took almost two hours. I populated a column with rand() and then recalculated the worksheet 1000 times. It took Excel 2007 twice as long to do the calculations. In another test, I copied cells 10,000 times to another sheet. It tok Excel 2007 almost three times as long to do the copying. To make charts, Excel 2003 can make 100 charts in 8 seconds. Excel 2007 takes almost 4 minutes. We have one workbook that refreshes links fine in 2003. In 2007, refreshing links crashes Excel. Saving and opening files seems to take twice as long. So far Excel 2007 is slower at everything Bob Flanagan Macro Systems http://www.add-ins.com Productivity add-ins and downloadable books on VB macros for Excel "Gary Keramidas" <GKeramidasATmsn.com wrote in message ... i am just curious if anyone sees a substantial degradation of speed when using vistax64/2007 vs xp/2003. i was on the beta for both vista and office 2007, and refuse to use either. i dual boot. when i run an app under vistax64/2007, it takes 4 seconds to complete, while under xp/2003 it's maybe a second. i know it doesn't seem like much, but everything i run is slower. this particular app loads and closes about 10 workbooks while it populates a schedule and does some other things. i personally think they're both useless and i'm glad i got them for free. someday when i feel like punishing myself, i'll install my 32 bit version of vista and see if it's any better. -- Gary |

Bob
Have MS been in touch to get your models? A couple of things for sure. 1) Some calcs can be significantly sped up by turning off multi-threading when that is not possible (Excel OptionsAdvancedFormulas) 2) The .xlsb (binary format) is optimized for speed 3) Any interactions with VBA will slow things down considerably as the multi-threading engine is not added to VBA hence Excel will need to hop in and out of modes For linking, again, Excel uses a totally different model and some things have changed. For example, with the new grid if you had a range name of ABC123, this is no longer valid and XL has to change all references to that to _ABC123 to stop it clashing. All range names starting xl are no longer valid as XL uses these for internal tasks, so again this will cause issues.

Yes, I was contacted late yesterday by email by MS. Sounds like they
definitely want to improve calc speed. I expect to hear back early next week. Bob "Nick Hodge" wrote in message ... Bob Have MS been in touch to get your models?

trust me, screenupdating is not the problem, it's turned off.
