Hey, I Was Wondering if anyone could tweak my connection.
Windows Xp
1. DSL
2. Connection: Bell Sympatico High Speed

SpeedGuide.net 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 TCP Receive Window (RWIN) = 65340
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 65340

RWIN is a multiple of MSS
Other RWIN values 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 TCP Window limits you to: 2614 kbps (327 KBytes/s) @ 200ms
Your TCP Window limits you to: 1045 kbps (131 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 115 hops
TTL value is ok.

Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON

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

Lan Browsing speedup - optimized
QoS: NonBestEffortLimit - 0
ToS: DisableUserTOSSetting - 0
ToS: DefaultTOSValue - 80
MaxNegativeCacheTtl - 0
NetFailureCacheTime - 0
NegativeSOACache Time - 0
LAN Request Buffer Size - 32768
Then select "Apply Changes" and reboot to take effect

To do a tracert, click 'Start' and then 'Run'. Type "cmd" into the box and click 'ok'.

A DOS black screen will appear. Type after the C:\>

tracert www.yahoo.com

and press enter key

When test is completed, move mouse cusor to the DOS black screen, click right and choose 'select all'.

Move mouse cursor to the Quick Reply box of this forum, click right and 'paste'.

The 3 ping times at hop 2 which is your modem are way too high. I suspect you have placed your modem near to some other electrical device. Relocate your modem a few feet away from any other electrical device, including the router or comp tower.

Power off comp, router and modem for a few minutes. Then reboot and test speed.

[QUOTE=trogers;1967513]Use the following with TCP Optimizer:

NetbtPriority - 1 not 8
Lan Browsing speedup - off not optimized
QoS: NonBestEffortLimit - 1

that's the only thing to do... Like in Europe!!!
