Just so I understand, are you're saying you get 78% compression with gzip6, but
75% of your data is compressible or 75% compression is possible. Where
does the 75% come from?

Another useful feature might be a wildcard "excludefromcompression"
directive so you could say:
excludefromcompression {
pattern = *.zip
pattern = *.gz
pattern = *.mp3
pattern = *.mpeg
pattern = *.flv
}
This might avoid wasting time trying to compress the unccompressible while
gaining the compression ratio on those files which gain from it?
On the other hand, perhaps it would complicate the job or the volume layout
too much to mix compressed with uncompressed data?
