I have a moderately complex Module (cell is about half a page long) that 
sets up 12 coupled linear equations; Solve[]'s these equations for two 
of the variables in terms of 10 others; and plots that variable vs one 
of the parameters in the equations.

The first time I call this module after opening Mathematica, the plot seems to 
appear much more quickly than on subsequent calls.  Anything I can do or 
should be looking for to improve this:

Clear[]ing all the variables at the start of the module doesn't seem to 
help.
