[opensuse] Performance of "cut" and "uniq"
by Jeff Janes 02 May '12

02 May '12

The "cut" binary that comes with openSUSE-12.1 is much slower than the "cut" I get by building from the coreutils srcpackage files that are from the openSUSE-12.1 repository. i | coreutils | package | 8.14-3.1.2 | x86_64 | openSUSE-12.1-Oss i | coreutils | package | 8.14-3.1.2 | x86_64 | openSUSE-12.1-12.1-1.4 | coreutils | srcpackage | 8.14-3.1.2 | noarch | openSUSE-12.1-Source The difference in performance is erased by setting LANG=C (the default is en_US.UTF-8), which change makes the installed binary much faster but doesn't change the built-from-source binary performance. See examples below. "uniq" seems to be in the same boat as as "cut". Is it a known issue that building from source lets the CPU safely take advantage of short-cuts to make things faster even under UTF-8 that a packaged binary cannot? Or perhaps is there a bug in the build-from-source that makes it faster, but somehow unsafe for UTF-8? perl -le 'my $x="x"x1024; print "123456,$x" foreach 1..1e6'| /usr/bin/time cut -d, -f2 |wc -c 71.93user 1.36system 1:13.58elapsed 99%CPU (0avgtext+0avgdata 3328maxresident)k perl -le 'my $x="x"x1024; print "123456,$x" foreach 1..1e6'| /usr/bin/time ~/coreutils_suse_source/bin/cut -d, -f2 |wc -c 3.81user 0.85system 0:05.08elapsed 91%CPU (0avgtext+0avgdata 3104maxresident)k perl -le 'my $x="x"x1024; print "123456,$x" foreach 1..1e6'| LANG=C /usr/bin/time ~/coreutils_suse_source/bin/cut -d, -f2 |wc -c 3.79user 0.89system 0:05.08elapsed 92%CPU (0avgtext+0avgdata 2368maxresident)k perl -le 'my $x="x"x1024; print "123456,$x" foreach 1..1e6'| LANG=C /usr/bin/time cut -d, -f2 |wc -c 3.68user 0.89system 0:05.00elapsed 91%CPU (0avgtext+0avgdata 2432maxresident)k Cheers, Jeff -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] git commits are seen in konversation
by Bogdan Cristea 01 May '12

01 May '12

I have noticed that if I am connected on konversation to a channel and I am commiting using git while working on a branch with a similar name as the konversation channel, each time I commit to the remote server these commits appear in konversation. Is there a way to disable this benhavior ? thanks -- Bogdan -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] digikam broke
by sc 01 May '12

01 May '12

a relatively recent update upgraded digikam and now it won't start -- gives a message: QSqlDatabasePrivate::removeDatabase: connection 'ConnectionTest' is still in use, all queries will cease to work. digikam: symbol lookup error: digikam: undefined symbol: _ZN4KIPI21ImageCollectionSharedD2Ev looking at digikam's website i see a post in response to someone with the same problem: <quote> libkexiv2 shared library installed on your system is not updated with digiKam. Typically, your digiKam have been compiled with a libkexiv2 more recent, and this lib have not been updated on your system. It's a broken resolved dependecy from your distro. Contact your linux distro team to solve the problem...

[opensuse] KDE hangs on rsync
by George Olson 01 May '12

01 May '12

Howdy all, I run rsync in a console (BASH) from time to time, usually from a script file. I have found that on my KDE 4.8.2 box that KDE hangs up in the following way from time to time. It won't switch desktops when I click or use the Alt-function key key stroke, it won't show the popups from plasmoids, and it won't switch applications using alt-tab or clicking on them. In effect, it makes multi-tasking impossible for the duration of the rsync. It usually hangs for about 5 minutes and then anything I have clicked on during that time will pop up and it will function ok for about a minute or so before hanging again. In 4.7.2 I remember my machine going slow when using rsync, but not totally hanging. I just upgraded a week or so ago. Here is my system: Box #1: 12.1 | KDE 4.8.2 | AMD Athlon X3 | 64 | nVidia 8500GT | 4GB RAM I have not tried running my rsync script in a tty instead of Konsole, so I don't know if the issue is with Konsole or with KDE in general. What other information do I need to post here to help communicate the problem?

Webpin doesn't work any more since 11.3. Pascal doesn't seem to find the time, and nobody else took over maintenance of the server's part of that service, either. Google for "webpin opensuse" and read the first few relevant posts for more context. Use http://software.opensuse.org/search to search in OBS, and http://packman.links2linux.org/search to search in Packman repositories you don't have enabled.
