Thread: AMD A8 5545M APU

  1. #1

    Default AMD A8 5545M APU

    hi, newbee here, I have a lpatop with the processor on the title, 16 gb ram and a 333MHZ bus. it should be a lightning fast computer unfortunately linux is loading and doing almost everything pretty slow.
    I think, and this is only my best guess, that it is not using all four of the cores in the quad core processor. is that even a possibility ? or maybe there is something else keeping it slow.

    thanks to anyone answering this.

    Hi
    What does the output from the command lscpu show?

    What about the cpu frequency?
    Code:
    zypper in cpupower
    cpupower frequency-info

    Hi
    So cpu info looks good, all cpu's present etc.

    The following will show the frequency info for all of them;
    Code:
    cpupower -c all frequency-info
    So what about boot time?
    Code:
    systemd-analyze
    Can you describe some more detail about what is going slow, disk
    access, starting apps?

    linux-mjq4:~ # systemd-analyze
    Startup finished in 5.113s (firmware) + 3.510s (loader) + 7.113s (kernel) + 22.892s (userspace) = 38.629s

    mostly what I see is that it take some time to access any folder in dolphin. applications are starting promptly but unfortunately windows 7 on a lap with less resource is doing all of this quiker.
    also boot time is slower than expected, especially once it reaches the small kde window with the hdd and other icons on it, it's like it is loading the desktop.
    if I was to hybernate the system, it tkaes some time to load the pages. not sure if it is a 5500 or 7500 rpm disk.
    also I took an sd card and copied pictures from it to my hdd under OS13.1 it took significant amount of time, and we are talking about merely 5GB on a class 10 sd card.
    thanks. sorry i took so long to answer. i didnt know you guys would be online and would answer so quickly

    Hi
    So now look at the following;
    Code:
    systemd-analyse blame
    I'm sorry I don't know much about KDE as I use Gnome....

    The above command should narrow down the slow booting. This system is only a dual core with 8GB of ram;
    Code:
    Startup finished in 4.934s (firmware) + 29ms (loader) + 3.027s (kernel) + 2.258s (userspace) = 10.249s
    So the first time is BIOS, not much can be done about that, second time is the bootloader, I have it set to hidden and default since it's only a single boot system. In your case this can be variable. The last two should be tweakable, I don't use plymouth for a start, boot time so quick it's gone so quick, so why bother.

    Lets see what the blame output is like first before apply some tweaks.

    if you look up amd a8 5545M it is a quad core. when I run the system hardware information from yast which is like the configuration on gnome it give me 4 cpus under cpu. like the same a8 cpu 4 times.
    I think we are up to something with that statement.

    Hi
    Your cpu is 4 cores (cpu's) with 2 threads per core equals 8, so no issues with the system recognizing what you have?

    So your hard drive is 1TB at 5,400rpm, since windows is probably on partition sda2, sure it will be fast..... can you post the output from;
    Code:
    lsblk
    To see what's where on the drive as you seem to have numerous mount points. The further out on the drive, the slower access will be... So are you running lvm?
