General discussion related to Cable Modems, DSL, Wireless, Fiber, Mobile Networks, Wireless ISPs, Satellite, or any other type of high-speed Internet connection, general issues and questions here. Review and discuss ISPs as well (AT&T / SBC, BellSouth, Bright House, CableOne, Charter, Comcast, Covad, Cox, Cablevision / Optimum Online, TMobile, Verizon FIOS, Shaw, Telus, Starlink, etc.)
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default Receive Window (RWIN) = 373360
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 46670
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:
Your RcvWindow limits you to: 14934.4 kbps (1866.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 5973.76 kbps (746.72 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = OFF
Time to live left = 50 hops
TTL value is ok.
Timestamps (RFC1323) = ON
Note: Timestamps add 12 bytes to the TCP header of each packet, reducing the space available for useful data.
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349)= 00000000
Running Win98SE applied 2 patches from this site.
Did anyone got something like that from this?
THX
btw... I was able to download a 50Mb file in 55 sec at 913kb/sec
Welcome to Speedguide , I'm assuming you would like assistance in tweaking your internet connection? If so please read the Help & Tips link in my signature and answer the questions at the top.
If your max speeds, as determined by your ISP, are too fast. You won't reach the max speed, unless you do apply those speed patches.
By too fast, lets say a 6mbit/sec cap might only download about 1.5 mbit/sec without the patches applied to the Win98se computer.
Those numbers are only estimates, but the use of patches to maximize your speed is the correct operation of your broadband connection.
The patches will NOT reconfigure your modem to download faster than your account is configured to download by your ISP. What the patches do, is to configure your TCP/IP settings in your registry to operate as smoothly and fast as your connection and speed cap allows.
