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.
