Slow Audio Conversion

[Taddeusz]

The information on the on-the-fly audio conversion indicates that it shouldn't affect ripping speed. However, on my system it significantly slows things down. I'm running the Linux version of MakeMKV. What could be causing this to happen?

I just completed ripping a movie using audio conversion and it took 5 hours. What gives?

I thought this might be chalked up to my CPU, an i5 3470. But using QSV in Handbrake on the same system I can convert a 45min BD video to 160x120 with 640kb AC3 audio in about 2-3min. So I don't understand why this is taking so long.
