New benchmark test!
Inspired by gnorpf's test I cooked up my own test.
This test does not require any download and is not dependant on audio drivers/latency/cpu-limit, however it does introduce disk access but that should be pretty insignificant.
Do like this:
Load all the demo songs (12 in all) and render to disk, measure the time it took to render each (using a stopwatch or similar) from pressing "Export" to the progress dialog dissapears.
Sum up the times and you got a nice figure to use as a measurement.
Important: load the songs one by one, and export at 44 kHz, 16 bit, closing the songs in between so you only have one song open at any time.
