Comcast needs tweaking please
I'm on the Comcast 8/768 tier that will see an increase in the coming days. I am now scoring between 9.5-12 on speed tests. I'm told that number can and will go up to 16. These are my results with the analyzer. Thanks for your recommendations. I also prefer cablenut, so if anyone could transfer this info and the result of the test into a .ccs file it would be greatly appreciated.TCP options string = 020405b4
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) = 17520
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 17520
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
256960 (MSS x 44 * scale factor of 4)
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: 700.8 Kbps (87.6 KBytes/s) @ 200ms
Your TCP Window limits you to: 280.32 Kbps (35.04 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
MTU Discovery (RFC1191) = ON
Time to live left = 115 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = OFF
IP type of service field (RFC1349) = 00100000 (32)
Precedence (priority) = 001 (priority)
Delay = 0 (normal delay)
Throughput = 0 (normal throughput)
Reliability = 0 (normal reliability)
Cost = 0 (normal cost)
Check bit = 0 (correct, 8th checking bit must be zero)
DiffServ (RFC 2474) = CS1 001000 (
- class 1 (RFC 2474). Similar forwarding behavior to the ToS Precedence field.
