| TCP options string = 020405ac0103030201010402 |
| MTU = 1492 MTU is optimized for PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput. |
| MSS = 1452 MSS is optimized for PPPoE DSL broadband. If not, consider raising your MTU value. |
| Default TCP Receive Window (RWIN) = 17424 RWIN Scaling (RFC1323) = 2 bits (scale factor: 2^2=4) Unscaled TCP Receive Window = 4356 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 a multiple of MSS Other RWIN values that might work well with your current MTU/MSS: 63888 (up to 2 Mbit lines, depending on latency. MSS * 44) 127776 (1-5 Mbit lines, depending on latency. MSS * 44 * 2) 255552 (2-14 Mbit lines, depending on latency. MSS * 44 * 2^2) 511104 (8-30 Mbit lines, depending on latency. MSS * 44 * 2^3) 1022208 (25-60 Mbit lines depending on latency. MSS * 44 * 2^4) |
| bandwidth * delay product (Note this is not a speed test): Your TCP Window limits you to: 697 kbps (87 KBytes/s) @ 200ms Your TCP Window limits you to: 279 kbps (35 KBytes/s) @ 500ms Consider increasing your RWIN value to optimize TCP/IP for broadband. |
| MTU Discovery (RFC1191) = ON |
| Time to live left = 48 hops TTL value is ok. |
| Timestamps (RFC1323) = OFF |
| Selective Acknowledgements (RFC2018) = ON |
| IP type of service field (RFC1349) = 00000000 (0) |

Below is a compact version of the results without specific recommendations, useful for sharing your current settings. Feel free to post in our forums with any questions you may have.
Optimize Your Connection
The TCP/IP Analyzer results provide packet header information from the TCP 3-way handshake between your computer and our server. The information above can be used to fine-tune TCP/IP settings and optimize your internet connection.
Detailed information on optimizing your network-related settings is available in our Broadband articles and TCP/IP Tweaks Articles.
We have also developed the free TCP Optimizer program to help apply the optimal settings automatically: SG TCP/IP Optimizer
