That's approximately what I've seen as well. However I have read articles that says that Calc, in average, is 10×-100× slower than Excel (however I am not sure what version of Excel they were referring to, but it was '97 or a more recent version.

Try autofilter with 20 columns and 2000 rows (which is not very much and should not be a problem, and IS not a problem with Excel). It's truly terrible with Calc!

I just have to add that in most cases, issue reporting works very well. At least mine were taken seriously and many of the issues, especially the most important ones that I reported, was corrected. So, the question is this - I think Calc has a serious flaw that will > stop potential users with big spreadsheets from using it (it is about to > stop me, anyway).

I have been talking about this for years, so there are a lot of people on this list by now who think that I am a very annoying person... Unfortunately, every time you argue that Calc is slow with big spreadsheets, someone always will tell you that jobs like that SHOULD be done with Base rather than Calc. In some cases it's probably true, I guess. I really like most things with OpenOffice.org, so I continue to use it, even though I have MS Office '97 on a CD pack, just because I think OpenOffice.org is so much better and it doesn't appear so annoying to me that MS Office '97 - 2003 does (I never tried the 2007 version, but it looks annoying on the screen shots I've seen... ;P). If Calc was at least 10× faster, compared to the current speed, I would be even more happy about my choice. These days I actually don't have much of a choice either, since I threw MS Windows of from my window ;D and there is no Linux version of MS Office. And MS Office is still too expensive in my opinion.
