Hallöchen,
ich habe bei www.speedguide.net nochmal unter anderem meine Einstellung überprüft und bekomme nun gesagt dass meine MTU nicht optimiert sei.Dabei habe ich mit ping -l MTU IP -f -w 10000 meine MTU getestet und schrittweise auf den richtigen Wert eingestellt.Jetzt weiss ich nit mehr was ich glauben soll.Das Ergebnis siehe unten.

TCP options string = 020405480103030201010402
MTU = 1392
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1352
Maximum useful data in each packet = 1352, which equals 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) = 261360
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 65340
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
519168 (MSS x 48 * scale factor of 
259584 (MSS x 48 * scale factor of 4)
129792 (MSS x 48 * scale factor of 2)
64896 (MSS x 4
bandwidth * delay product:
Your RcvWindow limits you to: 10454.4 kbps (1306.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4181.76 kbps (522.72 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 122 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC201 = ON
IP type of service field (RFC1349)= 00000000
