What Amiga Active actually said was
"The tests were conducted on an A4000/060 fitted with a graphics card.
This gave ideal conditions for the internal serial port. Using a slower
processor, or AGA particularly, would result in a reduction in speed for
the standard port and an even greater advantage for the I/O cards."
The reason for only testing on an 060 machine was that the PSU failed on
my A2000/040. The internal port uses the CPU far more than a card, so
the slower the CPU the worse the internal serial port. This is
especially true for web browsing when the CPU has got so much else to
do, like decoding graphics.

No graphics card and a slowish CPU? You'll benefit from a serial card
more than anyone else.

When I added a serial card to my 030/25 machine, the improvement was
remarkable. Not only did download run faster, but the jerkiness caused
by the serial using all available CPU power disappeared.

Time is an illusion but never so much as whem you're using a modem.
