Been there, done that.
Many years ago, it took me more than a week (and required the help of
an ARM instruction set guru) to come up with an assembly language IP
checksum routine for the ARM that out-performed the somewhat naive
NetBSD "C" version. When we switched to the FreeBSD stack (and a
newer compiler) a few years later, my assembly code got tossed out
because was no longer any faster than the C version.
