Won't affect CPU utilization.

Yes, absolutely.  Use the USE_SSE_EVERYWHERE=yes   and 
BUILD_SSE_OPTIMIZATIONS=yes  options to scons to build.  Then run
ardour with the '-o' command line flag.  You should see a message on
the terminal showing that the optimizations are enabled.

Won't affect CPU, but will help disk throughput issues on *really*
high track counts.
