RTFM on poll(7d) and use that instead of select(3C). The poll(7d) interfaces don't return a bit vector equivalently sized to your file descriptor set. Instead, it returns only descriptors with actual data or other actions on them. This lowers your overhead substantially. Just make sure you remove descriptors from poll(7d)'s list when you close them. It's all there in the man page.
