Tweak Test Results

Post by cablenut »

Lobo wanted to see my tweak test here it is:

TCP options string = 0204059c01010402

MTU = 1476

MTU is not at an optimal value... Consider increasing your MTU to 1500 for optimal throughput.

MSS = 1436

Maximum useful data in each packet = 1436, which seems to be equal to MSS.

MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 63184
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 63184

RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
252736 (MSS x 44 * scale factor of 4)
189552 (MSS x 44 * scale factor of 3)
126368 (MSS x 44 * scale factor of 2)
63184 (MSS x 44)

bandwidth * delay product:

Your RcvWindow limits you to: 5054.72 kbps (631.84 KBytes/s) @ 100ms
Your RcvWindow limits you to: 2527.36 kbps (315.92 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1010.944 kbps (126.368 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = true

Time to live = 245 hops

Timestamps (RFC1323) = false

Selective Acknowledgements (RFC2018) = true

IP type of service = x

Unscaled Receive Window = 46720

RWIN is a multiple of MSS

Hmm... Is QoS of 111 the best ?
