Well I found a post on dd-wrt.com
(http://www.dd-wrt.com/phpBB2/viewtopic.php?t=341) which suggested I should be
able to do better than the bandwidth numbers I was getting, so I spent this
evening experimenting. While digging through the DD-WRT settings, I discovered
that I had firewall logging enabled; disabling it resulted in an immediate
improvement to 13.4kb/s down, 1888kb/s up, and a reduction in max Load Average
to around 3.5.

That result motivated me to implement a change I had been meaning to make for a
while. A few months ago, I bought a Buffalo WHR-G54S, which is based on the
later Broadcom 5352 chip rather than the old 4712 chip of the WRT-54GS, and I
had been keeping it in reserve for testing, so I decided to see how it would
handle the new load. I upgraded it to DD-WRT v24 (released a few weeks ago),
configured it identically to the existing box, and swapped them out. The
bandwidth numbers remained the same, but the Load Average dropped to just a
little over 2.0 even with the link maxed out.

So it seems that the older hardware can do a pretty good job of utilizing the
current "premiere" domestic internet offerings, but newer hardware does it with
a little more "headroom".

Cheers,
Jon.

15Mbit/s down and 2Mbit/s up. However, when I try to use all that available
bandwidth, the Load Average on my WRT-54GS running DD-WRT v23 SP2 spikes to over
4.50 and the throughput maxes out at about 10Mbit/s. I thought this might have
been due to my QoS settings, but I see the same results even if I disable QoS.
To its credit though, the box does keep up, and does continue to manage the QoS
admirably even with that load.
