[LAU] optimizing jackd build

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/ 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 | 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
