Hoce u takvim situacijama da je problem sa MTU...

TCP options string = 020405780103030201010402
MTU = 1440
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 = 1400
MSS is not optimized for broadband. Consider increasing your MTU value.
Default TCP Receive Window (RWIN) = 65800
RWIN Scaling (RFC1323) = 2 bits (scale factor: 2^2=4)
Unscaled TCP Receive Window = 16450

In Windows 7, unless "TCP/IP Auto-Tuning" is disabled, only the Current TCP Window is displayed. Use the latest TCP Optimizer for tweaking.
You seem to be using Google Chrome. Note that Chrome can modify the TCP Window for sockets it creates under some OSes, and therefore servers may not get your correct RWIN value. You may want to test with a different browser. FAQ
RWIN is not fully optimized. The unscaled RWIN value is lower than it should be. Also, RWIN being close to and above 65535 does not justify the header overhead of enabling TCP 1323 Options. You might want to use one of the recommended RWIN values below.

RWIN is a multiple of MSS
Other RWIN values that might work well with your current MTU/MSS:
64400 (up to 2 Mbit lines, depending on latency. MSS * 46)
128800 (1-5 Mbit lines, depending on latency. MSS * 46 * 2)
257600 (2-14 Mbit lines, depending on latency. MSS * 46 * 2^2)
515200 (8-30 Mbit lines, depending on latency. MSS * 46 * 2^3)
1030400 (25-60 Mbit lines depending on latency. MSS * 46 * 2^4)
bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 2632 kbps (329 KBytes/s) @ 200ms
Your TCP Window limits you to: 1053 kbps (132 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 107 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)

Ako imas ADSL, dal si u PPP profilu stiklirao "CHANGE TCP MSS"?

Evo probaj sa ovim pravilom... moze da pomogne a nece da skodi
