Perhaps you should use timer to profile some of the (uncompiled)
functions, to see which take the most time. (Use timer_info to get
the timing information.) Then you might selectively compile them. If
that makes things slower, then you can post the code for people to
look at to see why compiling made things slower.
The translator (compiler) has some known issues. I also don't know
how well timer and timer_info actually work.
