    hi list,
    i read some threads in the ardour forum about optimizing the jackd
    build, so i would like to find out, if i can build jackd here with
    more
    optimizing ...since i think that more optimizing is better than less
    optimizing??

    the way i am building jack until now is simply:


    ./configure --with-default-tmpdir=/dev/shm/


add --enable-dynsimd to turn on SSE. Helps a LOT.

    when i run configure like this, i turns:

    jack-audio-connection-kit 0.103.0 :

    | Build with ALSA support............................... : true
    | Build with FreeBob support............................ : false
    | Build with OSS support................................ : true
    | Build with CoreAudio support.......................... : false
    | Build with PortAudio support.......................... : true
    | Compiler optimization flags........................... :
    -DREENTRANT
    -O3 -fomit-frame-pointer -ffast-math -funroll-loops -march=i686 -mmmx
    -msse -mfpmath=sse

but for me with this line, sse seems to be turned on already?
i just added the option you mentioned, but the configure output is the same.

cheers,
doc

    | Compiler full flags................................... :
    -I$(top_srcdir)/config -I$(top_srcdir) -I$(top_srcdir) -D_REENTRANT
    -D_POSIX_PTHREAD_SEMANTICS -Wall -g -g -O2 -I/usr/include/nptl
    | Install dir for libjack + backends.................... :
    ${exec_prefix}/lib/jack
    |
    | Default driver backend................................ : "alsa"
    | Shared memory interface............................... : "System V"
    | Install prefix........................................ : /usr/local


    the processor type in the kernel config here is 'Pentium M' but i
    don't
    know if the '-march=i686' could be changed with something like
    'pentium M'.
    since i am using a self made kernel, only a little help in this issue
    would help me a lot.

    cheers,
    doc
