compression question

[Lloyd Dupont]

I'm using #ZipLib to compress some data.
I wonder what's better:

- 1. produce a big (tar) file (concatenation of multiple stream) and gzip it
- 2. gzip all my element str and tar the whole bunch

Depends on how you will use your element strs.
AFAIK gzipping the whole bunch will result in smaller tar size as compared
to every element being gzipped.

However, if you're using not all the element strs, then more efficient will
be to have multiple gzips in one tar - you will be able to use parts of data
withour decompressing whole tar...
