Happy, but..........

[kalbo]

Hey folks!

Finally got the DSL line up and running (I'm happy), (but) the results are less than expected = 163 inbound/109 outbound. Before I start going "download crazy" with all the great tweaks on this site, can anyone take a look at my default settings. Any advice would be appreciated. By the way, I'm not very technical-NEWBIE!!! Thanks!!!

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
Maximum useful data in each packet = 1452, which equals MSS.
MSS is optimized for PPPoE DSL broadband. If not, consider raising MTU to 1500 for maximum throughput.

Default Receive Window (RWIN) = 17424
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 17424
RWIN is 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:
Your RcvWindow limits you to: 696.96 kbps (87.12 KBytes/s) @ 200ms
Your RcvWindow limits you to: 278.784 kbps (34.848 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.

MTU Discovery (RFC1191) = ON

Time to live left = 56 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 0000000

What are your actual caps from your ISP? Download the TCPOptimzer and do the following:

Settings tab:

select - dsl pppoe
check custom settings
network adapter selection - your NIC
check modify all adapters
maxmtu - 1492
TTL - 64
TCP Receive Window - try 31944/50820 or 63888
MTU Discovery - yes
Black Hole Detect - no
Selective Acks - yes
Max Dup ACKs - 2
TCP 1323 Options - uncheck both boxes

Other Settings tab:

Max Connections per Server - 20
Max Connections per 1.0 Server - 40
Lan Browsing Speedup - optimized

Then select "Apply Changes" and reboot to take effect.



:D ;)

Actual caps are set at 1.5 mb/128 kb. Unfortunately I'm not at home, but I wil try the new settings as soon as I get home. I also just got off the phone with pac bell tech support, and they suggested to remove any electrical item around the modem and/or if the phone jack is parallel to a power outlet and within 3 inches, he suggested to move to a different jack. I'll try the above options and I will report back on the results.

Thanks

Try "mnosteele52" recommendations. Additionally for best tweaking advice you can post in the Tweaking forum, that is all they talk about there.
