Hi
Currently use WinXP Pro SP2.
Connected using D-Link 504G. V2

These are the TCP/IP Analyser results:-

TCP options string = 020405840103030201010402
 
MTU = 1452
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.
 
MSS = 1412
MSS is not optimized for broadband. Consider increasing your MTU value.
 
Default TCP Receive Window (RWIN) = 256984 
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled TCP Receive Window = 64246 

RWIN is a multiple of MSS
Other RWIN values that might work well with your current MTU/MSS: 
519616 (MSS x 46 * scale factor of 8)
259808 (MSS x 46 * scale factor of 4)
129904 (MSS x 46 * scale factor of 2)
 64952 (MSS x 46)
 
bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 10279.36 kbps (1284.92 KBytes/s) @ 200ms
Your TCP Window limits you to: 4111.744 kbps (513.968 KBytes/s) @ 500ms
 
MTU Discovery (RFC1191) = ON
 
Time to live left = 50 hops
TTL value is ok.
 
Timestamps (RFC1323) = OFF 
Selective Acknowledgements (RFC2018) = ON
 
IP type of service field (RFC1349) = 00000000 (0)

What should i put into TCPOptimizer So i get fast P2P, Web surfing, Online Videos etc.

Also iam finding it hard to decide which is my network adapter.

1] Intel PRO/1000 PL Network Connection --IP address 10.1.1.2
2] Intel PRO/1000 PM Network Connection --IP address 192.168.1.48

Which country are you in? What speed did you pay your ISP to give you?

I live in New Zealand. Here there are copper wires used for broadband and the speed i pay for is 7.6MBPs. which i never get.

Try the speedtest of our website. Choose the test server in New Zealand:

Hi
I have carried out these tests during night when only few people are using there net.

I have done it 4 times to be more accurate.

No. What you have posted are the Summary reports. I need the report under the 'Staistics' button that shows your round trip time and the quality of your connection.

After the nitro test has been completed, click the 'Statistics' button and the report will pop-up.

Your round trip time (latency) is very high at 1177ms. Normal range from NZ to the US should be 280-350ms

Power off your router and connect your comp directly to the modem, reboot and do the nitro test again to see if this round trip time can fall to normal values.

Do a speedtest here as well during peak and offpeak times. Choose the test server in Auckland and note your latency values. We can then compare your local latency and those to the US:

You will also need to know how far you are located from the central office(CO) of your ISP. You can give them a call to find out.

After a distance of 1.5km, the distance will affect speed inversely, with zero speed at about 6 km from the CO.

Posted: **Mon Nov 20, 2006 6:19 am**

this is During off peak

iam roughly 2-3km away from the exchange.

Posted: **Mon Nov 20, 2006 6:55 am**

Do the TCP Analyzer again and post. Let's see if your MTU has increased. Also do the nitro test to check your round trip time for off peak time.

Your previous peak hour round trip time was 587ms. This test shows value almost double that. Your MTU is set at 1452, perhaps being fixed by your ISP.

Applied the settings. Any further tweaks i shuld try?. i do alot of p2p

Only one suggestion for P2P. Use the PeerGuardian 2 free software to help filter off unwanted connections, available at this http://phoenixlabs.org/pg2/

What speed did you pay to get? What type of router and modem are you using? Has your ISP upgraded to ADSL2+ system?

No they havnt upgraded to adsl2 or anything.my router is dlink dsl504g. its just that there is a les load on from this isp
