[fluid-dev] CPU usage

(Microprocessor use is about the same for both Jack(fluidsynth + Jack) and CoreAudio (fluidsynth by itself): see the
twofiles attached with this message.)

Thats a bit of CPU usage (~ 60%), were you pushing the synth during those tests?

No, I played back the MIDI file of a drum pattern (attached below) using the following command

%fluidsynth -a coreaudio(or jack) ~/Music/sf2files/Vintage.sf2 ~/Music/MIDI_files/drum_patterns/ROCK.MID

Attachment: ROCK.MID
Description: MIDI audio

I used the following script to obtain the test results.

# logscript.sh: script used for benchmarking fluidsynth playing back a MIDI file

echo $HOST
echo CPUs: `sysctl -n hw.ncpu` Vector Unit: `sysctl -n hw.vectorunit` Clock Speed: `sysctl -n hw.cpufrequency` Hz
uptime | sed 's/^[ ]*//'
top -l 10 -ocpu -R -s 2 -n 10

Best Regards.
