Bug Description

It'd be great to be able to use compression formation implementations which allow multicore CPU usage (e.g. `pigz` for gunzip, `pbzip2` for bzip2, etc.). Imo there's no argument against using them by default because most user just will see an significant increase of speed with some decent default values for parallelization options (`-p` of `pigz`, etc.) based on the CPU (cores).

This seems to be fixed in Ubuntu 16.10 based on simple observation (as opposed to a systematic test).

Right, I was confusing this with `nautilus`' archive creation/compress feature. I guess that parallelization depends on the compression algorithm used, but `file-roller` doesn't even use parallelization for gzip for which there's a parallel algorithm out for years, maybe decades.
