There's actually a restriction to ~64k *subdirectories* in a directory. But none on the number of files. And with the b-tree directories ext3/4 have been using for a long while accessing a directory entry is going to be cheaper than accessing a dirent in a subdirectory. So I think you're just prematurely optimizing at the wrong end.
