Oh, I should add that this is all running at 44.1kHz.

OK, this is not any kind of official benchmarking, but here's a rough
performance estimate of ChucK on the Raspberry Pi:
Setup:
Raspberry Pi Model B, no overclock, running Raspbian, 3.6.11+
USB sound card (little PnP device, <$10)
No monitor or keyboard; logged in via ssh
Testing multiple oscillators:
Up to 10 simultaneous SinOsc: no problem
10-12 mild glitching
Testing multiple shreds:
Using OTF examples, 6 shreds at once, no problem
7 shreds, major gapping
Testing LiSa:
LiSa-munger1 example works for up to 24 voices at once!
-------------------
Overclocking should improve performance. I expect that unplugging the
ethernet cable and auto-running a patch would help too.
Overall, I'm pretty impressed with its capabilities!

Yes, it compiles and runs nicely on the Pi. I'll try a little
performance test and get back to you shortly!

I've run into this problem too while compiling ChucK for the
Raspberry Pi.
I admit: In the back of my mind, I still view the Raspberry PI as a
very capable embedded controller. So I'm happily agog at what it's
really capable of.
Do you have ChucK running on the RPI? And if so, what's a rough
assessment of its performance, e.g. how many voices can it synthesize?
