Is this a good use for "compile"

New scheme user here.

Suppose I'm writing a spreadsheet. The user inputs a formula for a cell.

The plan is to use guile's peg parser to convert the formula into a lambda expression, which I then compile in order to speed-up subsequent processing.

So, suppose I convert the user's formula to a list, which turns out to be, for example: '(lambda (x) (+ x 13)) and compile it and save it in a formula table:

(hash-set! my-cell-formulae some-cell-ref (compile '(lambda (x) (+ x 13))))

So I can I expect a speed-up by having done the compile, as opposed to an eval?

I assume the answer is "yes", but I wanted to check.
