Your posts are all over the map, Ted. In an earlier post to this thread, you wrote: <quote> 10 years ago, it made sense. Now? </quote> So which is it? Did it make sense 10 years ago or did you find in "the late 1990's" that it wasn't worth it? > >A couple of years ago, I was working for a wholesaler who used EDI for the majority of the orders. >The app updated an order file and deleted entries as the orders were processed. >So, it was at least 67% writes. > >The app speeded up when we removed compression. You have provided one example of an application that performed worse with compression to support your conclusion that it is never worth the cost. Ron has provided examples to support his contention that it sometimes provides performance benefits.
