Yes, there are several ways to cut down build time, as long as you're 
prepared to accept some compromises.

Letting SCons generate a ninja build file, and using ninja for builds 
most of the time, is fine.  You can also use the 
--implicit-deps-unchanged option, which says not to rescan for 
dependencies.  Both approaches work if you know you haven't changed the 
structure of the project, such that the dependencies might change. If 
they do, just rerun SCons normally (or in generate-ninja-file mode), and 
you can go back to using the speedups.

There are some other tricks here:
