https://bugzilla.novell.com/show_bug.cgi?id=719027 https://bugzilla.novell.com/show_bug.cgi?id=719027#c0 Summary: any network transfers pause and restart after some time, connection speed goes up and down Classification: openSUSE Product: openSUSE 12.1 Version: Milestone 5 Platform: x86-64 OS/Version: SuSE Other Status: NEW Severity: Major Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: mpapis@gmail.com QAContact: qa@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:6.0) Gecko/20100101 Firefox/6.0 upgraded from 11.4 32bit to 12.1 milestone 5 64bit. I have problems with getting consistent network speed, it looks like it stops/pauses transfer for some time and restores it in few long seconds, in rare cases connection was timed out (eg. in zypper install). I had similar problems with dns (UDP?) in 11.4 and was using dnsmasq to overcome it. Reproducible: Always Steps to Reproduce: 1. go to speedtest.net, start test 2. go to speedtest.pl, start test 3. go to test.mm.pl(my provider), start test 4. pingtest.net, start test 5. for (( i=1 ; i<=100 ; i++ )) ; do echo test:$i; /usr/bin/time nslookup niczsoft.com 8.8.8.8 >/dev/null ; done Actual Results: it is hard to use network, pages show problems with loading, network is slow, installing packages timeouts or takes a lot longer connection goes up and down (see attachment), sometimes can not connect at all, even the test page loading is affected - the test pages not always loaded fast and smooth, sometimes they did not loaded at all or showed errors. Sometimes the stops/pauses continue after second or two, in most cases it continues before timeout, but sometimes it timeouts too, and when timeout is not implemented/handled properly it waits forever (over 5 minutes). pingtest.net errored on me few times, it only first ping response for packet lost test ... but when running ping to different servers from command line i get quite stable responses. nslookup in most times responds very fast (50ms - process spawning time) but tests 13,28,29,34,36,37,42,63,71,89,100 took 5, 10 or 15 seconds - 5s has to be internal timeout in nslookup as running with --timeout=2 had identical result (5,10,15) Expected Results: fast network operation I have tried to do most of the same tests earlier(11.4 32 bit) and all were working, the same tests on second computer with windows work as expected. I have 12Mbps connection, and can not use it even in half (avg in tests was bellow 4). During installation(upgrade) process everything worked fine, over 1000 packages downloaded and installed in less then an hour, the system was booted from Network installation iso cd put on USB memory stick - the only difference I see there was no NetworkManager involved. As mentioned on beginning I had similar problems with DNS(UDP) connections earlier https://bugzilla.novell.com/show_bug.cgi?id=613833 , right now I'm still use dnsmasq and I get delays on first time domain name resolution, any subsequent calls are fast. Also maybe this bug is related http://bugzilla.novell.com/show_bug.cgi?id=718736 ? Not sure if this might be related I always disable IPV6 during installation (I do not have access to any IPV6 capable network).
