bamafamily Posted February 21, 2005 CID Share Posted February 21, 2005 Hey Van Buren, I had tried your Version 4 settings for my Cable connection based on 3500/384. I believe it gave a pretty big window..(of course that was assuming people were running SP2) On your recomendation, I am using TCP Optmizer until I decide if I wanted to install SP2. (Optimizer uses a setting of 256960) I saw you released Version 5, so I went in and looked at it. I see you put in an SP1 version and I noticed the "3000" setting in MSS1460/SP1 dropped the Window size considerably... Just wondering the method to your madness...lol thx bama Quote Link to comment Share on other sites More sharing options...
VanBuren Posted February 21, 2005 CID Share Posted February 21, 2005 well the SP1 3000 file using a TcpWindowSize of 64240 and that works very well, it might not give the best speed on a speedtest cos there is less burst compared to a TcpWindowsize of 256960 however the true speed, will be the same for 90% of the users downloading a large file also the 64240 value has no windows scaling and gives a snappy webrowsing compared to the larger value thats why i choosed it the 3500/384 file from Version 4 also using a TcpWindowSize of 64240 but has a AFD tweak, so with SP2 it will report a RWIN of 437248 the TcpWindowSize can be calculated if you know your MSS ( MTU-40 ) and your maximal bandwidth in KB/s and the worst possible ping to your gateway http://www.dslnuts.com/bitsbytes.shtml the hard thing is to determin the latency, this is diffrent for diffrent users aswell but ive learned that a value between 150-300 works very well. all my tweakfiles is not calculated, i sometimes use values that i know work very well wit that type of connection VanBuren Quote Link to comment Share on other sites More sharing options...
bamafamily Posted February 21, 2005 Author CID Share Posted February 21, 2005 Thx Van Buren, I calculated my RWIN from the link you gave and came up with 58400..Close enough to your max of 64240... For now, I will probably just use 64240 until I change my OS settings...thx bama Quote Link to comment Share on other sites More sharing options...
MICROWAVE Posted February 21, 2005 CID Share Posted February 21, 2005 bamafamily, Yeah I have used both settings I have been using 64240 for about 2years when I first set it with TCP Optimizer it suggested the 256xxx but I found that 64240 works best for me and dont see much difference with that or the 58xxx value....
