I've gone over lots of posts and tips and improved my connection so now I'll post and ask if anyone sees anything else that needs to be done
Embarq 5.0 dsl service
windows xp pro
zyxel 660r modem (bridged)
Agnitum Outpost firewall
TCP options string = 020405b40103030201010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default TCP Receive Window (RWIN) = 256960
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled TCP Receive Window = 64240
RWIN is a multiple of MSS
Other RWIN values that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4) <-- current value
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):
Your TCP Window limits you to: 10278 kbps (1285 KBytes/s) @ 200ms
Your TCP Window limits you to: 4111 kbps (514 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 49 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
