The is a method of determining the optimal size of the Physical Log in the Administration manual, have a look at that. I don't see that you have a problem because of chunk writes, I believe you have a problem because of the length of time to checkpoint. _/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/ Gordon E.
