-One of the easiest things to do is run a profiler on the code. This lets us see if there is something in the runtime or compiled code that is dominating the runtime, and possibly slowing things down. This isn't a catch-all - for example, it can't show us if a compiler optimization is needed. But it helps paint a picture of what is going on.

+A compiled Cyclone program is just a regular C program so we can use the standard GNU tools for profiling and debugging.
 
 To get started we change `Makefile.config` in cyclone-bootstrap to enable profiling. The `-O2` option in the lines below are replaced with `-g -pg`:
 
     CFLAGS       ?= -g -pg -fPIC -rdynamic -Wall -Iinclude -L.
     COMP_CFLAGS  ?= -g -pg -fPIC -rdynamic -Wall -I$(PREFIX)/include -L$(PREFIX)/lib

 Well that's interesting, `tail` is spending all of its time computing `Cyc_length`.

+Again, Cyclone compiles programs to C, so we can use `gdb` to debug them and figure out how `Cyc_length` is being called.
