Pablo,

I still don't think I usderstand what you are asking. Are you asking if the time it takes to save the data is longer with a transaction than without one? The asnwer to that would have to be yes as the transaction si doing more than the simple TableUpdate. All of teh TableUpdates are done and then the data is committed. The committing of the data is the actual writing to disk. Both with and without transactions the TableUpdate and teh write to disk must occur, with teh transaction there is the one more step of logging the transaction actions so they can be committed together at once. So transactions must take longer. How much longer is probably not measurable.
