Hallo zusammen!
Kann mir jemand sagen was die richtigen Jumbo Werte sind wenn man WIn7 zusammen mit einer FB6340 betreibt?
Laut KBW Mitarbeiter wären das 7168.
Ist dies korrekt?
Hier alle Werte.
TCP options string = 0204055c0103030201010402
MTU = 1412
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 = 1372
MSS is not optimized for broadband. Consider increasing your MTU value.
Default TCP Receive Window (RWIN) = 66364
RWIN Scaling (RFC1323) = 2 bits (scale factor: 2^2=4)
Unscaled TCP Receive Window = 16591
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.
For optimum performance, consider changing RWIN to a multiple of MSS.
Other RWIN values that might work well with your current MTU/MSS:
63112 (up to 2 Mbit lines, depending on latency. MSS * 46)
126224 (1-5 Mbit lines, depending on latency. MSS * 46 * 2)
252448 (2-14 Mbit lines, depending on latency. MSS * 46 * 2^2)
504896 (8-30 Mbit lines, depending on latency. MSS * 46 * 2^3)
1009792 (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: 2655 kbps (332 KBytes/s) @ 200ms
Your TCP Window limits you to: 1062 kbps (133 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 111 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)
Uuuups. Falsches Forum.... Kann ein Mod das bitte rüber schieben? Danke :smile:
