>I'm mainly a VFP programmer, but one request I have the owner insists in having an Access application for his sales orders information. He's talking about having it as single-user app at first and down the road have several people use it. The question is, how many users will an access database support without taking a performance hit?
> I read an MS article that states Access can have 20+ users with no problems, but an Access guy I run into every once in a lunch time tells me that he starts taking performance hits at 4-5 users on an small inventory control app. TIA


Well, it depend on a lot of things
1-Lot's of queries ?
2-Lot's of writes ?
3-Lot's of append ?

As a non official rule, I can say that 10 users is the max with an app that have transactions appening all the time.
