the easiest way to think of a 6148 is that it's like 8 individual 1G
ethernet hubs connected into a 1G switch.
Now, now - a hub would flood everything to all other ports. ;)
But yes, this card is not one of the architectural high points in the

Once you visualise it in
these terms, you can immediately see that performance is going to be awful.
The best thing to do with these boxes is retire them aggressively. It's
generally cheaper to swap them out with 1U boxes than it is to pay the
power (and consequently cooling) bill, if you look at it over a lifetime
of several years.
