Hi [H]arders,

I upgraded my Internet to Virgin Media's 100Mb and have been getting some very odd test results while debugging my router's speed.

I have this simple config:

LAN>>>>>>Router>>>>>>Modem>>>>>>Internet

Testing Website:
http://www.speedtest.bbmax.co.uk
http://www.bbc.co.uk/iplayer/diagnostics

The Modem can be configured as a Router or Modem and is currently a Router for testing purposes, but I get the same results in Modem mode. I can therefore crudely test the router for throughput speeds by comparing the inside and outside of the router. These are the results:

Modem (Outside) - ~100Mb from bbmax and ~100Mb from bbc
LAN (Inside) - ~100Mb from bbmax and ~50Mb to ~65Mb from bbc

I'll be performing a packet capture tomorrow sometime to see what the traffic is, but before I do, I thought I'd ask if anyone can explain why testing with BBC gives me 35% to 50% reduced performance over the router?

FYI, the router is a E3000 with DD-WRT. I have tested this with another router that gives similar, but differed results.
 
Its supposed to... If I recall correctly 150Mb throughput. I am however getting 100Mb using bbmax.
 
not tested or used speedio before. Speedtest.net never peaks at these speeds here, so its not that reliable. in my experience, BBMax is the most reliable here, same goes with BBC iplayer diagnostics.
 
I am also from the UK and have maxed out 100mbps links on the London speedtest servers

I'm not based in London and don't use there server. I will give them a go though.

Are you behind the modem via a dedicated router/firewall? What are you getting with BBC diag?
