Jel razume neko ovaj test:
TCP options string = 020405b401010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default Receive Window (RWIN) = 32767
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 32767
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):
Your RcvWindow limits you to: 1310.68 kbps (163.835 KBytes/s) @ 200ms
Your RcvWindow limits you to: 524.272 kbps (65.534 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = OFF
Time to live left = 55 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000
Koliko sam ja shvatio trebalo bi da promenim RWIN, ali gde i kako se to menja i koju vrednost treba da unesem. Inace sam vec radio tweak sa nekim programcicem i bas mi je on podesio RWIN 32767
