If the reason for the threading is performance, then it seems to me that you are recalculating the statvfs structure, which is more readily available via the module Filesys::Statvfs (or one of its brothers).

The *nix command df -k uses that same system-internal structure, reporting it back one line per file systems as device, blocks, #used, #available, %capacity and mount_point.

On a huge Sun Solaris system with hundreds of file systems, I just got the result back from df -k in only 0.02 seconds and would expect a Perl program using such a Filesys module to perform comparably well.

Update: If your needs are indeed limited to what df does, Filesys::Df will be easier to use or Filesys::DfPortable if the code also has to run on any of Mac OS X, Unix, Linux, Windows 95 or later and so on.

More update: In addition, to get per user per file-system stats, you could also enable disk usage quotas, without actually limiting usage, but to enable retrieval of such information via the Quota module.
