That option was implemented IIRC, there must be a bug, fill a bugzilla report, thanks !
Even it would be implemented, is it sure that compression with old gzip and pigz always gives the same files? Here it doesn't: rudi@quant:/tmp> time ~/tmp/pigz-2.1.6/pigz -c hist.csv |md5sum 95311648cd2813bfd2d9a2a265b9c9de - real 0m8.839s user 0m34.222s sys 0m0.987s rudi@quant:/tmp> time gzip -c hist.csv |md5sum 736ed650389ca836c6f7aec93c071eb3 - real 0m29.950s user 0m29.797s sys 0m0.359s Don't know whether I'am doing wrong but sometimes I rely on it that gunzip bla.gz gzip bla restores the same bla.gz as before. If gzip will be replaced by pigz then I can never do that again with any of my existing .gz files. BTW you can see that user time is 15% higher with pigz so compression per core cycle is worse. cu, Rudi -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
