I got a 7x performance improvement in a performance-critical component at Arbor Networks within a couple weeks of starting there just by profiling, finding malloc/free at the top of the profile, and switching to an arena allocator. I have other malloc stories, but that's the simplest. I've learned to fear malloc.
