Not necessarily. If I understand correctly what Tim means, he's talking
about an in-memory compression of several blocks by several separate
threads, and then - after all the threads have compressed their
but gzip format is single stream. dictionary IMHO is not reset every X
kilobytes.
parallel gzip is possible but not with same data format.
By the way in my opinion grzip (in ports/archivers/grzip) is one of the
most under-valued software. almost unknown. compresses faster than bzip2,
with better results, it is very simple and making parallel version is
trivial - there is just a procedure to compress single block.
Personally i use gzip for fast compression and grzip for strong
compression, and don't use bzip2 at all
