It greatly speeds compilation to not do all those drivers that I don't need. Sound cards I don't have Latest that created packages without errors. I'll be upgrading to 4.0 kernel shortly. https://bugzilla.redhat.com/show_bug.cgi?id=1199312 > > 5. Etc. > > How anybody can help in this way, man. > I don't see how those have any relevance. All the answers to them would do is be noise or distraction. This is at a meta level above that, about the design and control level, rather than the implementation details. I guess I am assuming that the kernel programmers have done their job, and the kernel functionality is abstracted from the underlying hardware. Especially for x86 architectures. I think Heinz has put his finger on the issue in his response: a single process is limited to a single core. But, if that single process can spawn other processes, which is what 'make -j6' should be doing, why would that be true? I'll be following up in my response to him. Thanks for taking an interest, and I'm not trying to be hostile, but I honestly don't see how answering your questions helps. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
