Optimizing KDE 3.1.x

Posted by timothy on from the wringin-out-seconds dept.

David Lechnyr writes "This article goes into detail on optimizing KDE for speed. Typically, most distributions include pre-compiled binaries of KDE which are optimized for an Intel i386 computer. Chances are that you're running something faster than this; if so, this should help you tweak the compile process to speed things up a bit."

    Using prelink will also provide additional optimization.

    See http://www.sourcemage.org/ All source, downloaded from the authors site and compiled to the settings and optimizations YOU choose.

    Absolutely. Using either of these technologies allows one to compile any piece of software using the best possible optimizations for your system.

    Experimental? Come on. Maybe -O3 and then a series of other additional optimizations beyond that are experimental. But the sane optimizations most people use are not experimental. I, myself, default to:

    -march=athlon-tbird -Os -pipe -fomit-frame-pointer

    Btw, compiling everything from scratch is hardly "unstable". That's what FreeBSD does. Furthermore, memory optimizations often-times increase system-stability, by reducing the likelihood of situations where there isn't enough RAM. Furthermore, some of the USE settings increase stability by eliminating compiled-in support for crap that you don't use. If you don't use something, and support for it is compiled in, it's just useless crap that has the potential to reduce stability.

    I'd love to, but I'm stuck on a dial-up connection. Is there any way to get a snapshot of all Gentoo on CD-ROM or DVD? I've been checking out the Linux stores without any luck.

    "Intel's compiler brags that it is totally compatible with gcc and gives a 30% speed increase to the final result on an Intel processor."

    That's only true for pre-GCC 3.1 releases. GCC 3.2 can produce code that rivals that of Intel C++. GCC 3.1 and 3.2 contain lots and lots of x86 optimization improvements.
