| |
Hello,
I tryed different linux distributions on a computer with an Intel Core 2 Quad and I noticed that the 64-bit versions was at least 10 times slower than the 32-bit versions, to boot the system took over 20 minutes in 64-bit mode and then even scrolling text at the command prompt felt slow, however Vista 64 boots as fast as Vista 32 on the same computer. So I would like to ask if this is a known problem or if there is some simple misstake I can have done.
I used live cd's from gentoo and ubunto and at least ubuntu has a rather new kernel, also dmesg doesn't show anything strange, for example is the bogomips figure the same as when booting in 32-bit mode. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
