Even it would be implemented, is it sure that compression with old gzip and pigz always gives the same files? Here it doesn't:
Of course it doesn't. Gzip gives no guarantee that it does in its man page, so if you rely on that, it's a mistake.
BTW you can see that user time is 15% higher with pigz so compression per core cycle is worse.
That's called cache pressure. It happens when more than one process is running. Run four gzips concurrently, you'll probably experience the same increase. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
