You only get compression if the other end supports some of
the "free" compression algorithms supported by pppd .
Usually your ISP only supports MS-Stac compression :(
Some ISDN TA's support this in hardware, and analog modems have V42b.
So the best is to use the hardware version.
If you dial-up with ppp to a unix/linux box, there might be a chance
that some type of compression can be enabled (ppp-deflate, bsd-compress,...)
I don't have any benchmarks, since I can not test this, but I
only know that you have to disable (software) compression in pppd if
you want to use hardware-compression with the ppp protokol in ISDN TA's
But usually some form of compression should be used.
With ms-stac (hardware) and one channel (64kbit/s or approx. 7.6 kbyte/s),
if I download a file with 1 million "*" or some easy compresseable html files,
an 230400bps seriel connection gets 100% used. (approx. 23kbyte/s).
I can't remember the values for 460800bps . But the "*"-file gets
over 40kbyte/s.
(Compressed files as tar.gz and zip do not compress any further)
