NDT test site for 20Mbs?

My cable ISP has increased my DL speed above 20 Mbs. This is great but I am having trouble finding a decent test site. All the NDT sites I used before (at 7 Mbs) either do not work, report a 10 Mbs sub-net or yield ridiculously low tested speeds. The Miranda NDT site shows about 5 Mbs but I can DL at more than 2 MBs (upper case B, Bytes - at lease 16 Mbs).

Anyone know of an NDT site that works at these speeds?

Thanks, John.

Go into the 'properties' of your network adapter card (NiC) and try setting speed & duplex to 100 mbps full duplex.

trogers,
Thanks for your reply, but I am not looking for help tuning. I am looking for an NDT test site(or some site) that returns diagnostic information (Statistics) that help me determine if I need to increase or decrease my RWIN (for example). I have one local test site that shows around 20 Mbs, but it presents no statistics.

Thanks, John.

Try this site: http://nitro.ucsc.edu/ or the others listed near to the bottom of the page.

Reports are under the 'More Details' and 'Statistics' buttons.

Thanks again for your reply, but I have tried all of those with no useful results. I got the following from the one you suggested:
This connection is network limited 99.83% of the time.

The theoretical network limit is 5.18 Mbps
The NDT server has a 50.0 KByte buffer which limits the throughput to 8.33 Mbps
Your PC/Workstation has a 339.0 KByte buffer which limits the throughput to 27.98 Mbps
Certainly not strong enough for testing a 20+ Mbs ISP.
Thanks, John.

Depending on where you are....I use a server near me...I've benched connections up past 80 megs...nyc.speakeasy.net

Thanks, YeOldeStonecat, that is a good one (Dallas). I tested at greater than 29 Mbs, but still no statistics as are given by the NDT sites.

Looks like time to give up, John.
