In that case you're pretty much bound by the time the directory
traversals help.
Using larger inodes will help you as we won't have to seek for the
external attribute block. Not filling a fs 100% will probably help by
reducing the fragmentaion, as will using larger directory blocks
as suggested by Dave.
A patch to improve the unlink path won't help the traversal speed
ever, though.
