Sorry Humpty - I confused the thread a little by bringing up lzop.  Lzop compresses *faster* (the fastest there is) but slightly bigger - from what stupid_idiot says, advdef compresses *smaller* (both as compared with gzip).

So different advantages with different progs.

But a major point is that advdef's format is still gzip-compatible - it just takes more time for compression, which should be fine just when making extensions.  So this seems to be more realistic to implement right away.

For Lzop, perhaps this would be great for backup/restore... though I suppose for people with larger backup.tar.gz's to grow even bigger.

Some reports using advdef:

Regular .tar.gz extension: ~50MB file (using gzip default -9 level)
Used: advdef -z4
~4 minutes; saved ~2%; ~1MB difference

hats:  a pedantic aside  - I don't think -9 is the default for GNU gzip.

wdef: Ah.. well I used tar zcvf... I think I meant it for the gzip default in GNU tar, because the size of that and manually using gzip -9 was the same (or is it?)
