=apologies:
my description of current practice was slightly misleading and has 
unfortunately distracted people from the pertinent question and the OP's 
topic and objective (from which I'd like to benefit).

=so to clarify:
my using tar does NOT have the specific objective of compression. It 
conveniently creates one handy tar-ball of a set of dump-files. I 
probably copied this idea from 'somewhere', eg a book; without thinking 
through the next/obvious further possibility, as raised by the OP...

=and now, back to my actual request:
has anyone checked which compression tool might do better than 'the 
others' when working on the likes of MySQLdump files?
(and ideally (and diverging from the OP's spec), I'd prefer that it to 
work on a set of files not just one at a time)
