 |
|
Currently, xz-utils is not MT. Neither is 7zip on Linux.
Does anybody know if there is a multi-threaded utility which can do LZMA compression? |

Using the -mmt flag with 7z (from app-arch/p7zip)?

And it doesn't work with -m0=lzma. It uses only 1 thread. |

Both CPUs (3 threads) on one of my systems are used if I run it like that:
| Code: |
7z a archive.7z somedir/ -m0=LZMA -mmt
|
Even if I don't give the -mmt flag it uses both CPUs except I explicitly add -mmt=off.
