How much effort would it take to optimize a /bin/sh? Would replacing uses of fork+execve posix_spawn be fast and portable enough? Even on Linux, performance sucks for me. I've been hoping dash can use posix_spawn (or using vfork directly) to see if that can help things. That won't help with subshells, though... (I'm back to using a Centrino laptop from 2005)
