VanBuren Posted January 29, 2005 CID Share Posted January 29, 2005 heya mistkron make sure you have 6000 768 file installed as it is, then read this post https://testmy.net/topic-1989.msg19795#msg19795 and finetune your TcpWindowSize and GlobalMaxTcpWindowSize 6000 Kbps = 6000 / 8 = 750 KB/s MSS = 1460 latency = the tweakfile using 250 ms the latency here suppose to be the worst possibleyou have to your gateway, try downloading several files and see what ping you get a normal ping is between 200 and 300 ms Web100 reports the Round trip time = 281.09 msec; the Packet size = 1460 Bytes; and There were 3 packets retransmitted, 35 duplicate acks received, and 29 SACK blocks received you had 3 packets re transmitted, measure the latency to gateway or try reducing the latency to 220 ms and see if the re transmissions stops.

mistkron Posted January 29, 2005 Author CID Share Posted January 29, 2005 sorry VanBuren , i think im a really slow learner or something. i dont get you. so what is it that i should do to "fine tune" my TcpWindowSize and GlobalMaxTcpWindowSize , 6000 Kbps = 6000 / 8 = 750 KB/s MSS = 1460 latency = the tweakfile using 250 ms what is this above for ? is it a guideline or instruction to put for the settings ? sorry mate , my bad Quote Link to comment Share on other sites More sharing options...
VanBuren Posted January 29, 2005 CID Share Posted January 29, 2005 http://thegamer.serveftp.com/FAQ.htm quote 25. Run this TCP analyzer http://forums.speedguide.net:8117/ 26. Find that MSS value eg 1460 27. Find 2 big files to download where you get full speed here is some fast servers [uSA users] ftp://ftp1.optonline.net/pub/test64 ftp://ftp.newaol.com/aol6.0/179902/setupaol60.exe ftp://test.tampabay.rr.com/ftp.50m.sav [EU users] http://ftp.sunet.se/pub/vendor/microsoft/ServicePack6/sp6i386.exe ftp://ftp.snt.utwente.nl/pub/games/urbanterror/urbanterror37_full.exe ftp://ftp.ltu.se/pub/misc/bf1942/maps/4maps4theaterswar_mappack.zip start the download when you use your maximal bandwidth, eg download 1 running 300 kbps + download 2 running 325 kbps = 625 kbps = 5 Mbps, ping your isp (for optimal ping to use later is the ping to your first hop). 28. Run this RWIN calculator http://www.dslnuts.com/bitsbytes.shtml in bandwidth field use your capped speed in Kilo Byte, so if you have 1500 kbps, split that in 8 (8 bit= 1 byte) and you get 187,5 KB/s, use the ping you got in #29 in latency field, and the MSS value from #28. 29. Now you have a optimized RWIN value. 30. Open cablenut adjuster in top left corner click open file, browse to VanBurens cablenut settings folder choose the connection you have and OS and also the folder with your MSS, now dubbleclick on the file that suit your advertised speed eg Cable & DSL 3500 384. If your calculated RWIN is above 65535, you need to set Tcp13230pts to 1. 31. Now you got a few values set in adjuster, change TcpWindowSize and GlobalMaxTcpWindowSize to that RWIN value you calculated before. Also change TcpRecvSegmentSize and TcpSendSegmentSize to your MSS.

mistkron Posted January 29, 2005 Author CID Share Posted January 29, 2005 sorry , ive encountered yet another problem . im only download like 18-20 kb/sec from both the big files i download. do i still use the info i get ? or is something wrong Quote Link to comment Share on other sites More sharing options...
VanBuren Posted January 29, 2005 CID Share Posted January 29, 2005 also always use the 2992 KB test when testing speed here Quote Link to comment Share on other sites More sharing options...
VanBuren Posted January 29, 2005 CID Share Posted January 29, 2005 download other files, close to where you live but i suggest you try values instead, this can take some time, first try 220 ms then try 200, now you see a diff in speed and know where you heading if speed decrease, try a larger latency eg 300 ms VanBuren Quote Link to comment Share on other sites More sharing options...
VanBuren Posted January 29, 2005 CID Share Posted January 29, 2005 i made 3 files for you with a latency of 200, 250, 300 try em out, remember to click save to registry every time you change and reboot VanBuren Quote Link to comment Share on other sites More sharing options...

VanBuren Posted January 29, 2005 CID Share Posted January 29, 2005 and well , ive tried downloading files from se.asia ( asia based websites ) and im getting a capped download rate around 820 KB/sec. then there is not much to do, the route between you and testmy.net is long and if you get loss on a 300 ms ping then it will slow down alot VanBuren Quote Link to comment Share on other sites More sharing options...

mistkron Posted January 29, 2005 Author CID Share Posted January 29, 2005 thats the best it can go ? so the bandwidth 6500/384 is underacheiving ? Quote Link to comment Share on other sites More sharing options...
VanBuren Posted January 29, 2005 CID Share Posted January 29, 2005 you have a very long route to testmy.net and will never reach 6500 Kbps what you can change in those files is DefaultRecive window, so it match 6500 and not 6000 as download cap the new value is 6500 / 8 = 813 x 1024 = 832512 VanBuren Quote Link to comment Share on other sites More sharing options...
