That fits my definition of insanity even if one knows the compilers output to the assembler well enough to stuff some of your own assembly tricks in. I have found a couple places where I can beat the compiler by 1/25th the execution time, in the compiler I am most familiar with. I took an rzsz build based on the Omen Tech source, from being able to process 275 characters a second on a 1.78 mhz cpu, to 720 cps on that same cpu & clock by sticking some of my stuff into the output file going to the assembler.
