Ciao a tutti! questi sono i miei dati. Ho una adsl 640. secondo voi (io nn ci capisco molto) è proprio penalizzante questo settaggio? considerate che prima ho fatto il test di vel. e andava a 570 kbps. ho un modem USB. se faccio salire il MTU a 1500, quanto deve'essere il MSS??
MTU = 1464
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 = 1424
Maximum useful data in each packet = 1424, which equals MSS.
Default TCP Receive Window (RWIN) = 17088
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 17088
RWIN is a multiple of MSS
Other RWIN values that might work well with your current MTU/MSS:
524032 (MSS x 46 * scale factor of 8)
262016 (MSS x 46 * scale factor of 4)
131008 (MSS x 46 * scale factor of 2)
65504 (MSS x 46)
bandwidth * delay product (Note this is not a speed test):
Your TCP Window limits you to: 683.52 kbps (85.44 KBytes/s) @ 200ms
Your TCP Window limits you to: 273.408 kbps (34.176 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
MTU Discovery (RFC1191) = ON
Time to live left = 121 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)
