This is on my roughly-6-year-old desktop, a 4-core AMD Phenom II X4 910e, Fedora 23 x86-64, a local ext4 file system mounted rw,relatime,seclabel,data=ordered on a hard disk. It's been this slow for ages (I've mentioned it here), and is why I typically don't bother running 'make check'. I prefer a 'make check' (or whatever) that takes less than a minute. This is so that I can test the change I just installed in my private copy of Emacs, before publishing it. I don't want to test in the background because then I lose my train of thought. I prefer testing while writing the ChangeLog entry. PS. I am getting due for a faster machine but not yet. I want an Intel Skylake so that I can verify that Emacs works with the new x86-64 hardware-based subscript checking implemented via GCC 5's -fcheck-pointer-bounds option. I also want ECC memory for reliability's sake. This combination isn't available yet for desktops, at least not in configurations I can afford. All this being said, I expect that Emacs 'make check' is slow for reasons unrelated to my 6-year-old CPU.
