Performance on PI 2

After getting version 0.8a up and running, I’ve noticed that performance after a fresh start seems decent (not great but workable). After letting it run for quite a bit, it degrades to the point where it requires over a minute to respond to the wake-word and skill. Is there any reason to believe that a PI 3 would make this any better?

It looks like the speech client is consuming an entire core while waiting for a wake word…

Update: Pi3 Model B has zero issues with performance. I guess the PI 2 was just under powered.
