Sar Posted February 16, 2006 Report Share Posted February 16, 2006 connection 512/256k seed 32 peer 50 what is the suppossed download speed?Network ok - followed everything on this forum but my download speed is around +/- 30kb/s Link to comment Share on other sites More sharing options...
Ultima Posted February 16, 2006 Report Share Posted February 16, 2006 Divide by 8 for each number, and you get your kilobyte/second speed. 64KB/s down, 32KB/s up. Might just be a slow torrent. Try the OpenOffice.org torrent. Link to comment Share on other sites More sharing options...
Firon Posted February 16, 2006 Report Share Posted February 16, 2006 Did you press Ctrl G and choose xx/256kbit? Link to comment Share on other sites More sharing options...
Sar Posted February 16, 2006 Author Report Share Posted February 16, 2006 With openoffice.org torrent I get around 45kb/s down.I did press Ctrl G and choose xx/256Kbit and lower setting without any improvement. Link to comment Share on other sites More sharing options...
Ultima Posted February 17, 2006 Report Share Posted February 17, 2006 Did you try that speed test in the Speed Guide? Maybe your ISP isn't really giving you your full bandwidth... Link to comment Share on other sites More sharing options...
Sar Posted February 17, 2006 Author Report Share Posted February 17, 2006 speedtest from several site including my ISP provider site shows the download speed 380kbps to 411kbps. My ISP provider says if it's around 70% of my rated line speed(purchased 512/256k)this is acceptable.But I do get a 45 to 50kb/s on a fast torrent.According to Ultima, "Divide by 8 for each number, and you get your kilobyte/second speed".And if this is true my download speed will be around 45 to 50kb/s.Any suggestion Link to comment Share on other sites More sharing options...
Ultima Posted February 17, 2006 Report Share Posted February 17, 2006 When you run the speed test, make sure you're not doing anything else with your net connection -- just the speed test. If you still get those results, then the ISP is indeed not giving you the speed they advertised. Link to comment Share on other sites More sharing options...
The Mighty Buzzard Posted February 17, 2006 Report Share Posted February 17, 2006 @Ultima: Untrue, you didn't factor in the protocol, DHT, or PEX overhead. Around eighty percent of his max 64kB/s (51.2kB/s) is all he can expect under peak conditions.@Sar: If you're getting 45-50kB/s, you're doing quite well for your connection. Think happy thoughts or spring for a fatter pipe. Link to comment Share on other sites More sharing options...
Sar Posted February 17, 2006 Author Report Share Posted February 17, 2006 Yes just the speed test. A survey done by a local newspaper not while ago in major towns across the country proved that the ISP is not giving the rated purchased speed. Here's the ISP statement,"Communications equipment vendors like to think in terms of low level ATM data rates without regard to the structure or content of the data. ATM is a protocol for transferring data between two points. Internet uses IP as the protocol for communicating, therefore, and in particular, TCP/IP. So your data is going over your DSL line via TCP/IP over ATM.TCP has an overhead in transmission that can be about 5-10%, but ATM overhead is more like 15%. So you can expect to lose up to 25% of your purchased speed at least when counting application data transfer rate. Making up a rule of thumb here: Given a broadband line speed, dividing by 8 and taking off 25% is a reasonable estimate of the maximum likely data download speeds (in bytes of data) you will manage to get.

The Mighty Buzzard Posted February 17, 2006 Report Share Posted February 17, 2006 That's more or less right. Losing bandwidth to overhead is just a fact of life. Dividing by eight is just converting units of measure, bits to bytes, no loss of anything there. If you want to save some math in the future, divide by ten and you have bits->bytes with overhead already factored in for most applications.

Firon Posted February 17, 2006 Report Share Posted February 17, 2006 ATM overhead is about 13% Link to comment Share on other sites More sharing options...
Sar Posted February 17, 2006 Author Report Share Posted February 17, 2006 According to dslreports.com ATM overhead is about 13% but not for my ISP provider.Any chances to improve speed with what I own right now Link to comment Share on other sites More sharing options...
Ultima Posted February 17, 2006 Report Share Posted February 17, 2006 ~45KB/s is decent for your connection. Remember, torrents don't always max your connection out. Microsoft's servers usually can though ;P@TMB: I wasn't talking about BitTorrent downloads. I was talking about the speed tests. Link to comment Share on other sites More sharing options...
