I _strongly_ suggest you setup one filesystem per directory.

That will help for directory locking but one node will still be faster
than the rest in your current setup. I see similar problems to yours
every time I have a FS mounted on multiple nodes and being written to,
which is one reason we try to keep FSes mounted on one node only.

Please elaborate on that. Others on the list will be able to help then. :)
