does jack say it's running SSE on startup?
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, doc
