tar - How to force "archive manager" (file-roller) to use all cpu cores? - Ask Ubuntu


i using ubuntu's archive manager (file-roller) compress (tar.gz) large files , directories.

often takes long time, because program uses 1 of 8 cpu cores.

is there way force archive manager use cpu cores?

i've been trying find answer question myself, , can report partial success: p7zip, while not maxing out cores, seems make quite bit of use of more one, @ least while compressing. on dual-core system, maxes out both cores, , on family member's quad-core, maxes out 1 core , runs other 3 @ half load, varying between 30% , 80% or so. extraction seems not multi-threaded @ all, though, maxes out 1 core , rest idle along.

i've tried installing various of multi-core capable compressors , creating links them /usr/bin, file roller ignored them. find in research hint on german forum (if goog's translation accurate) there apparently hard-coded paths in file-roller source, suggested replace original binaries in /bin links (theoretically command-line-compatible) multi-core replacements pigz, haven't felt daring enough try yet myself.
