Full Discussion: Full usage of CPU

Generating files is an expensive process and it's not a process that is cpu bound. Using ten disk drives would be more useful that 10 cpu's.

Also how many files in the directory. Creating file number 1001 in a directory costs a lot more than creating file number 2. Keep the ratio of files per directory as low as possible.

Look at the mounting options on the filesystem. Metadata is typically synced rather aggressively. There may be a way to give up reliability to get performance. For example with a vxfs file system on hp-ux you could set minchache=tmpcache.

Dist::Metadata::Dir(3pm)				User Contributed Perl Documentation				  Dist::Metadata::Dir(3pm)

NAME
Dist::Metadata::Dir - Enable Dist::Metadata for a directory VERSION
version 0.923 SYNOPSIS
my $dm = Dist::Metadata->new(dir => $path_to_dir); DESCRIPTION
This is a subclass of Dist::Metadata::Dist to enable getting the dists metadata from a directory. This can be useful if you already have a dist extracted into a directory. It's probably not very useful on it's own though, and should be used from "new" in Dist::Metadata. METHODS
new $dist = Dist::Metadata::Struct->new(dir => $path); Accepts a single 'dir' argument that should be a path to a directory. determine_name_and_version Attempts to parse name and version from directory name. dir Returns the "dir" attribute specified in the constructor. file_content Returns the content for the specified file. find_files Returns a list of the file names beneath the directory (relative to the directory). physical_directory Returns the "dir" attribute since this is already a directory containing the desired files.
