And 30 minutes to decompress. Very small, but very very slow.
For comparison, the complete history of Perl (Score:1)
So, I started with over a hundred megabytes of tarballs from history.perl.org, and got those down to 6MB of git pack. Once into the Perforce history, I was looking at reducing the ~400MB of Perforce repository even further. After my initial export, it was already something like 250MB of Git pack (I wrote the exporter to make best use of on-the-fly delta compression). I left a fairly aggressive repack on it going, and it took about 30 minutes and left me with these packs [utsl.gen.nz], which are MUCH smaller. The deco

I've long used 7-Zip when I'm forced to use a Windows system, but I've never used it's native 7z format (LZMA).
From a quick scan of Wikipedia it seems that the 7z format is LZMA compression with a 64-bit header and optional extras and the plain lzma tool as described by you here is a raw LZMA compression stream. They are incompatible in that the two tools can't yet process each others files, which is a shame.
I can see lzma files replacing bzip2 files in my archives now. How much smaller could CPAN be ma

It doesn't always compress tighter than LZMA but it's usually much faster.
