Everybody is taking my quotes out of context to mean a dozen different
things. Everything from "5.3 can't do more than 3 Mb at all" to
people saying they don't have the problem when they have far more
hardware or far less bandwidth than I do.
A P266 is *way* faster than a 486 133 MHz (4501). I can pull 6 Mb on
a 4801 (essentially a P266, though a Geode 266 MHz proc) and keep CPU
around roughly 30-40% max.
It's hard for most people to simulate the problem even if they do have
something as slow as a 486 133 since most don't have over 3 Mb of
bandwidth. A 4501 on b3 can do ~7-9 Mb, and b5+ can only do ~3.5 Mb
(this all can vary by environment, but those are good numbers for
If you stress test your hardware in a test environment (since you
don't have the internet bandwidth to max it out), you'll see the
severe performance drop from b3 to b5+.
I haven't tried anything that isn't NAT'ed, but the wireless to LAN
performance has been poor for several people (haven't really tested
mine) so that seems to be a problem as well. This does give me some
thoughts on things to try though.
