Correction: I did not bother to read far enough into the puff-piece press release to see that the DEC 8400 is not a mere $40K box. It has 10-processors and 6GB of RAM, which means the DEC probably jammed the entire datbase into memory, ie, no physical disk I/O.

By contrast, my linear extrapolation of 7580 tpm should be scaled up by 10 to 75,800 tpm which would be about 7-times _faster_, at least, than Sybase.

Even less impressed with Sybase now.
