I need help from a network expert. I would like to know my optimum XP Pro SP2 settings for my ADSL2+ line.

Calculating correct RWIN/GlobalMaxTcpWindowSize/TcpWindowSize, DefaultTTL etc.

Line specs/test results:

• Connection type: ADSL2+
  
• Cable length to DSLAM: 1350m (0,4mm)

• Actual maximum donload speed: 1,74 mB/sec*
  
• Actual avg. download speed: 1,68 mB/sec*
  
• Max packet size before fragmentation: 1472**
  
• MTU: 1500 (1472+28)
  
• Latency: min: 23ms, max: 30ms, avg.: 25ms*** (TTL: 251)
  

*Tested with DU meter and 2 running 700 mB downloads from ISP 100mbit ftp.

**ping www.uio.no -f -l 1472 (.no & no other bw. load)

***ping www.uio.no -n 100 (.no & no other bw. load)

Tweaks are to be implemented during UA installation.

I use Cablenut, perhaps you can find your answer there BoardBabe

http://www.cablenut.com/

You can then get the reg settings

I know how to set the reg keys like RWIN, but I need help calculating RWIN please.

I see but if you also get the extra Custom setting files and load them one at a time and you can get an idea of the calculation. XP DSL PPPoE 3000 384.ccs, DSL PPPoE 512 128.ccs

Perhaps not the easiest way but usable. These custom files work

Edit I have read somewhere what you're asking but its lost in my Favs
