I forgot to mention here, that the fluctuation was observed using Ubuntu 10.04 LTS (Lucid Lynx) Alpha 3 live-CD. ** Description changed: Binary package hint: ppp A mobile broadband download is very slow (only 10–20 % of what it is - supposed to be) in Jaunty, Karmic and Lucid-alpha2 (and also in Hardy - used in more modern computers, ie. P4->) 0.4–0.6 Mb/s, when the + supposed to be) in Jaunty, Karmic and Lucid Lynx Alpha 3 (and also in + Hardy used in more modern computers, ie. P4->) 0.4–0.6 Mb/s, when the theoretical max. speed of the affected ISP's plan is 3.6 Mb/s (in practise the speed is about 3 Mb/s in Windows Vista). To reproduce: Download an Ubuntu iso-image from a nearest mirror. In Hardy used with elderly PIII laptop (see Comment #2 for lshw) download speed is 250–300 kB/s, which is a good five times faster than in Jaunty (about 60 kB/s). This is a regression and performance issue related to download speed, which is at worst ten times slower on average compared to Windows OS's (40 kB/s vs. 400 kB/s). The extremely slow speed seems to be USB/3G modem independent (tested in Nokia CS-15, Huawei e1552, Huawei E230, Nokia cell phone 6220 classic, ...). Currently there is a Finnish discussions going on at http://forum.ubuntu-fi.org/index.php?topic=31241.msg244415#msg244415 http://forum.ubuntu-fi.org/index.php?topic=31241.msg244345#msg244345 Karmic: http://forum.ubuntu-fi.org/index.php?topic=29763.msg243897#msg243897 Interesting is that, when you download for example four Ubuntu distros in the same time, your download speed is approximately: 60 kB/s + 60 kB/s + 60 kB/s + 60 kB/s = 240 kB/s. When you cancel three of those downloads, you will continue with the "normal" Jaunty download speed that is surprisingly 60 kB/s. Some other day the individual download speed could be only about 40 kB/s. On the other hand, torrent download (several seeders) is quite fast: about 300 kB/s. Tested both near the capital city centre of Helsinki and also at the very edge of the 3G field at countryside. There is no diffenrence between locations. Tested with: NetworkManager and Wvdial (and by other people with umtsmon and vodavone-mobile-connect). No difference. Most probably these speed / network bandwidth issues are related only to one internet service provider called Sonera (TeliaSonera) in Finland. Nevertheless, last autumn the "HelpDesk" at Sonera did not comment this issue. - ProblemType: Bug Architecture: i386 DistroRelease: Ubuntu 9.04 ExecutablePath: /usr/sbin/pppd Package: ppp 2.4.5~git20081126t100229-0ubuntu2 ProcAttrCurrent: unconfined ProcEnviron: PATH=(custom, no user) SourcePackage: ppp Uname: Linux 2.6.28-18-generic i686 -- 3G download speed is very slow compared to Hardy on elderly PIII computers or Microsoft Windows OSs https://bugs.launchpad.net/bugs/525049 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
