understanding broadway code

[soliton4]

what does this mean?
avc.configure({
filter: 'original',
filterHorLuma: 'optimized',
filterVerLumaEdge: 'optimized',
getBoundaryStrengthsA: 'optimized'
});

has it got impact on performance? is there a docu?

It means that you ask the Broadway "source" code to be patched with optimized version.
You can put none, original and optimized (look at the Broadway source code for the possible values).
From my own measurement, it does not make any difference, since most of the time is spent in the decoding functions anyway.
