>                 Key: VFS-593
>                 URL: https://issues.apache.org/jira/browse/VFS-593
>             Project: Commons VFS
>          Issue Type: Bug
>    Affects Versions: 2.0
>            Reporter: Sam Halliday
>
> I did a YourKit analysis of a heapdump when running ENSIME, which uses VFS2, and I found
several GB (25%) of the heap was wasted on duplicated strings within VFS2.
> This could be averted by using `.intern()` on Strings that represent paths.
