You're splitting into parts which are far too small. Typically, a file is split into 20-50 parts, with 5 or 6 PARs for the set (acting as wildcards), but you can easily create 50 PARs and say "collect any 25". It's not designed for thousands of tiny parts; if people want to distribute thousands of files, they typically archive them up first, and split the archive. Most PAR operations are IO-bound (judging by drive thrashing, not from actual benchmarks). > Perhaps I should make my program 'par' command-line compatible! > OTOH, when you have so many small files it is not convenient. I don't really understand the use of allowing thousands of tiny parts. What's the intended end use? -- Glenn Maynard
