Re: [LAU] optimizing jackd build

now, since i recompiled with --enable-dynsimd it says:

...
JACK tmpdir identified as [/dev/shm/]
SSE2 detected
load = 0.2297 max usecs: 40.000, spare = 10626.000
...

looks like a nice hint??

what is about processor type and architecture?
are there more hints about optimizing?

cheers,
