10,000 what? If you mean rows then it would completely depend on the size of the row. At work our orderline table has over 16million rows atm. It's pretty damned quick so long you use one of the indexed fields otherwise it can get a little sticky. A couple of days ago I found a query lurking on one of the reporting db machines which had been running for almost 36 hours! I killed it, if there was anyone waiting for that I feel sorry for them but I haven't heard anything back yet.
