well after playing with sudo time installpkg --threads 2 libreoffice.txz
htop only see 1 core working
TIME see 98% cpu usage (Only 63% with a smaller archive imagemagick)
with --threads 2 or --threads 1, TIME give the same time.
Conclusion (beware I am particularly good for doing misinterpretation)
-hdd bottleneck (3 1/2 7200rpm 256Mo cache 100Mo/s...) ?
-to be able to use the decompression multithread, the archive must be created with -t2 or more ?
well after playing with sudo time installpkg --threads 2 libreoffice.txz
This thread might not be the right place for support questions about installpkg, xz and performance. People will probably be more willing trying to help in a separate thread.
Sooooo... when his new qdvdauthor is complete... it would make a great addition to -current.
It already works great on -current with qt6 and has just few little differences
in operation from the original which required the addition of qt3 from SBo https://slackbuilds.org/repository/1...ia/qdvdauthor/
____________
The WIP qdvdauthor v2.4.1 in operation built on and running on slackware64-current.
qt6-base need also to add this sed line in the SlackBuild, 'sed -i '/zstd CONFIG/d' cmake/FindWrapZSTD.cmake' (thank opensuse)
# Work around an issue with zstd CMake files (boo#1211566)
# TODO: Remove when the issue is fixed
this is needed because qt6-tools, failed to build with 'zstd-1.5.6'
Thanks. For some reason I keep running into this (both the upstream 6.7.0 and also pulled from KDE's git):
Code:
../../../../../../qtwebengine/src/3rdparty/chromium/third_party/mesa_headers/../../../../../../qtwebengine/src/3rdparty/chromium/ui/gl/gl_display.cc:945:10: error: x11 has not been declared
945 | return x11::Connection::Get()->GetXlibDisplay();
Hi, there are problems for adding Open MPI in Slackware? ( https://slackbuilds.org/repository/1...search=openmpi )
This package is needed as build/run dependency for many third parts packages and could increase the features of FFTW3, useful for many third part software used in research and technical areas, by adding the support to MPI-2 implementation with the option --enable-mpi in configure (this builds additional libraries and headers that include the support of fftw3 to MPI)
