The common experience is, that high level languages result in slow and
bloated code. But this must not be true. There is no reason for such
compilers despite laziness of developers (it's an expensive development).
For most modern processors hand written assembler will be slower than a
compiler output. The complexity of scheduling and computation dependencies
can be handled by a human in hundreds of hours, but a compiler can do this
in a few seconds in respect to all possible optimization methods.
You might produce a better code for a small time critical loop but not
overall.
