Recommended Posts

Here is my download test results.

Download Speed is:: 27 kB/s

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

Test Time:: Fri Jan 27 2006 21:58:37 GMT-0500 (Eastern Standard Time)

I have run virus tests, cleaned the registry, spyware scans, and I have CableNut but im not sure what settings to use for it considering its DSL Lite. Could anybody help?

TCP/IP ANALYZER

TCP options string = 020405ac01010402

MTU = 1492

MTU is optimized for PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.

MSS = 1452

MSS is optimized for PPPoE DSL broadband. If not, consider raising your MTU value.

Default Receive Window (RWIN) = 5840

RWIN Scaling (RFC1323) = 0 bits

Unscaled Receive Window = 5840

For optimum performance, consider changing RWIN to a multiple of MSS.

Other values for RWIN that might work well with your current MTU/MSS:

511104 (MSS x 44 * scale factor of 8)

255552 (MSS x 44 * scale factor of 4)

127776 (MSS x 44 * scale factor of 2)

63888 (MSS x 44)

bandwidth * delay product (Note this is not a speed test):

Your RcvWindow limits you to: 233.6 kbps (29.2 KBytes/s) @ 200ms

Your RcvWindow limits you to: 93.44 kbps (11.68 KBytes/s) @ 500ms

Consider increasing your RWIN value to optimize TCP/IP for broadband.

MTU Discovery (RFC1191) = ON

Time to live left = 53 hops

TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349) = 00000000 (0)

Your subscribed speeds are 256 and 128 Kbps and your test results are 170 and 93 Kbps. That means your comp is set at 67% and 73% of subscribed speed.

Try this ccs file to achieve 90% for both. Your target speeds are 225 and 115 Kbps. Always test with the largest file of 2992 kB.

I'm gonna tell u a lil secret!!...The people here...most want 2 help u but once they get tired of trying 2 figure out what is wrong with ur connection...They are gonna tell u this..."THAT'S ABOUT THE BEST YOU CAN DO ON THAT CONNECTION"...Which is bu!!$h!T!!...I have had the same exact connection u have 4 about...2-3 years now and had the same problem u are having...so i've had 2 experiment... and these are the best setting i came up with so far...GARUANTEED 2 WORK!!!!

Hi RaWDIZ,

I have tried your ccs file. Your file has set the RWIN value very high. This is okay if you have good line quality and when traffic in your ISP's network is not high.

But in instances of poor quality line or high traffic, a high RWIN will result in excessive packet losses and high retransmissions, thus slowing speed.

The correct tweak setting is to find a balance of RWIN value to adust PC throughput limit with the network throughput limit (both limits must be higher than advertised speed) and a correct TcpReceiveWindow size that will minimize packet losses and retransmissions.

An Example:

Advertised speed is 1500 download DSL

RWIN setting at 128480

Web100 reports the Round trip time = 169.82 msec; the Packet size = 1460 Bytes; and

There were 10 packets retransmitted, 56 duplicate acks received, and 66 SACK blocks received

The connection stalled 1 times due to packet loss

The connection was idle 0.57 seconds (5.69%) of the time

This connection is network limited 99.98% of the time.

Excessive packet loss is impacting your performance, check the auto-negotiate function on your local PC and network switch

Your PC/Workstation has a 125.0 KByte buffer which limits the throughput to 5.77 Mbps. The network based flow control limits the throughput to 0.72 Mbps.

RWIN setting at 64240

Web100 reports the Round trip time = 205.13 msec; the Packet size = 1460 Bytes; and

There were 15 packets retransmitted, 120 duplicate acks received, and 126 SACK blocks received

The connection stalled 1 times due to packet loss

The connection was idle 0.42 seconds (4.19%) of the time

This connection is receiver limited 6.65% of the time.

This connection is network limited 93.33% of the time.

Excessive packet loss is impacting your performance, check the auto-negotiate function on your local PC and network switch

Your PC/Workstation has a 62.0 KByte buffer which limits the throughput to 2.38 Mbps. The network based flow control limits the throughput to 2.44 Mbps.

This is the basis of how I select values for my ccs files and gauge optimum performance of the files.

Your PC/Workstation has a 499.0 KByte buffer which limits the throughput to 7.90 Mbps

The network based flow control limits the throughput to 0.31 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 'T1'
