Could also try /usr/gnu/bin/ls -U. I'm working on improving the memory profile of /bin/ls (as it gets somewhat excessive when dealing with large directories), which as a side effect should also help with this.
Currently /bin/ls allocates a structure for every file, and doesn't output anything until it's finished reading the entire directory, so even if it skips the sort, that's generally a fraction of the total time spent, and doesn't save you much. The structure also contains some duplicative data (I'm guessing that at the time -- a _long_ time ago, the decision was made to precompute some stuff versus testing the mode bits -- probably premature optimization, even then). I'm trying to make it so that it does what's necessary and avoid duplicate work (so for example, if the output doesn't need to be sorted it can display the entries as they are read -- though the situations where this can be done are not as often as you think). Hopefully once I'm done (I've been tied down with some other stuff), I'll be able to post some results.
