What ABI are you using in your ARM system? EABI? IIRC cairo does most
stuff with fixed point floats internally. Make sure you use the newest
releases (or even svn/git versions). About the freezes: if it's a system
freeze it's a kernel bug, if it's a big slowdown it may be a problem in
cairo or moonlight.
Note that moonlight has not been optimized for speed at all (we are
still in the early stages with it).
Running with mono --profile==default:stat may give some clues where the
time is spent (you need addr2line/binutils installed).
