Os pego aqui los datos que me a dado el optimizer.
TCP options string = 020405500103030201010402
MTU = 1400
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.
MSS = 1360
MSS is not optimized for broadband. Consider increasing your MTU value.
Default TCP Receive Window (RWIN) = 257040
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled TCP Receive Window = 64260
RWIN is a multiple of MSS
Other RWIN values that might work well with your current MTU/MSS:
522240 (MSS x 48 * scale factor of 8)
261120 (MSS x 48 * scale factor of 4)
130560 (MSS x 48 * scale factor of 2)
65280 (MSS x 48)
bandwidth * delay product (Note this is not a speed test):
Your TCP Window limits you to: 10281.6 kbps (1285.2 KBytes/s) @ 200ms
Your TCP Window limits you to: 4112.64 kbps (514.08 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 55 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)
Lo siento por el tochaco, sigo mirando y luego comento.
