The first time I booted, it took about 10-15 minutes on my 3GHz P4 laptop! I watched the gdm background slowly display over about 30 seconds. I thought it might have something to do with the new default timer frequency, which I set to 250Hz instead of 1000Hz (which is the default for pre 2.6.13 kernels). According to various online sites, 250Hz should still be just as usable, and may even use less power, increasing my battery performance... So I changed the timer frequency back to 1000Hz, recompiled and now it seems a little faster, but no where near 2.6.12. It now boots in maybe 5 minutes, and the gdm theme takes about 5s to display. glxgears (not maximised) gives me about 30 fps with a radeon 9700! I checked the frequency governor, and the default is still 'performance'. /proc/acpi/processor/CPU0/throttling shows the maximum frequency is active as per normal. Other kernel options I changed are: - support for software suspend added (could this be it? I definitely saw the message that no valid suspend was found in my swapfile, and /proc/swaps shows that I have swap enabled as per usual) - removed unnecessary SCSI drivers (I don't have anything SCSI) - removed SATA support (I definitely don't have SATA) Info: Dell Ispiron 9100, 3 GHz HT Pentium 4 2.6.12 and 2.6.13: SMP support for 2 processors included I've seen 1 post online about the same thing - slow running 2.6.13, so surely there must be some people in the world running it ok! Any help on this would be appreciated. TIA, -- Iain Buchanan -- gentoo-user@gentoo.org mailing list
