Vj compression only compresses headers, not the data portion of the packet. Predictor-1 compresses the entire packet. In both cases, the other end of your link must support compression. I turned off modem compression and enabled predictor-1 yesterday. Ping times to my next router went from 170Ms to 140Ms with a 21600 DCE link.
