My view would be that on modern computers switching to allocate from the
heap wouldn't make a big difference if it were changed. Modern heaps
have pools for small allocations to stop them fragmenting larger
allocations anyway. Someone would need to do a compressive test to know
for sure, these things often have knock on effects.. I've seen massive
slowdowns when someone switched malloc() to calloc() on MS-Windows!

Choice of malloc implementation can have a huge effect on execution
time. See this data

Some modern mallocs are good, but stack-based allocation is still better
a lot of the time. Especially for temporary variables that are just
going to be discarded after a few computations.
