Registry setting and analizer different

I installed the tweaks as per an earlier post several days ago. But when I checked on the analizer it's not the same.

Here is the results



TCP properties for IP = ()
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)
Notes: Read the Analyzer FAQ if the above is not your IP address.

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) = 17520
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 17520

RWIN is 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: 700.8 kbps (87.6 KBytes/s) @ 200ms
Your RcvWindow limits you to: 280.32 kbps (35.04 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
MTU Discovery (RFC1191) = ON
Time to live left = 117 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000



It shows the RWIN to be 17520 here on the analizer.

In cable nut adjuster it shows default receive window at 38400 and the send window at 32768.

What's going on and what am I missing? I did save to regisry and rebooted. I'm confused :confused:

in 2k/xp the default recive window is the tcp window size.

so basiclly in 2k/xp tcp window size is the setting the analyzer looks at.

Your settings are fine :thumb:

OK, thanks it just seemed to small of a number so i thought it wasn't being entered incorrect.
