i ran the tests from nitro, included my isp is Comcast and im supposed to have 6Mb service but every time i test i can never get above 4 my quality of servie is around 90%. ive used tcp optimizer andWEB100 Kernel Variables:

estimate = 40.3 based on packet size = 11Kbits, RTT = 276.42msec, and loss = 1.0E-6

The theoretical network limit is 40.3 Mbps

The NDT server has a 8192.0 KByte buffer which limits the throughput to 231.53 Mbps

Your PC/Workstation has a 125.0 KByte buffer which limits the throughput to 3.54 Mbps

The network based flow control limits the throughput to 3.58 Mbps

Client Data reports link is 'T1', Client Acks report link is 'T1'

Server Data reports link is '10 Gig', Server Acks report link is 'Ethernet'

used thier optimal settings. help please.:::.. Download Stats ..:::

Connection is:: 3417 Kbps about 3.4 Mbps (tested with 5983 kB)

Download Speed is:: 417 kB/s

Tested From:: https://testmy.net (server2)

Test Time:: Tue Feb 14 10:51:56 EST 2006

Bottom Line:: 61X faster than 56K 1MB download in 2.46 sec

Diagnosis: May need help : running at only 71.71 % of your hosts average (comcast.net)

Validation Link:: https://testmy.net/stats/id-GXB78I2CJ

Where are you located?

The reason you cannot achieve 90% speed at www.testmy.net is that your RTT to the US is too high.

"estimate = 40.3 based on packet size = 11Kbits, RTT = 276.42msec, and loss = 1.0E-6

The theoretical network limit is 40.3 Mbps

The NDT server has a 8192.0 KByte buffer which limits the throughput to 231.53 Mbps

Your PC/Workstation has a 125.0 KByte buffer which limits the throughput to 3.54 Mbps

The network based flow control limits the throughput to 3.58 Mbps"

Your RTT of 276 ms is limiting your PC throughput to only 3.54 Mbps.

If you try to increase buffer size to 250 Kbytes (DefaultWindowSize - 256960) your RTT will jump to 700+ ms raising your throughput to only 3.8-3.9 Mbps.

If you are located in the US, you need to check your line quality or possible electromagnetic interference on your modem and router.

If you are located overseas, it will be difficult to reduce RTT due to your distance and number of hops in getting to this test site.
