Unbelievably slow?

Question

So I have installed Elementary OS hearing how beautiful and lightweight it is. I'll agree it is very good looking but it's too slow in my computer. I'm pretty sure I have installed all my drivers properly.

My last OS was Windows 10, it was so fast. Chrome wouldn't take more than 3 seconds to launch, but it takes atleast 20-30 seconds for Elementary OS. It takes about 3-5 minutes before a CS:GO match can start for me. Games run well though. Freezing is another problem for me. It freezes outta nowhere and it's very fraustating. I atleast need to wait a minute for that. Opening terminal is also preferably slow. I did not install Elementary OS for that. Any possible reason why is this happening and how can I solve this problem?

Specs: i3-3220, 4gb ram, R7-240, H61m Motherboard.

Answer 1

Open terminal and type:

sudo lscpi.

or

sudo update-initramfs

You probably did not install the firmware for the GPU socket and did not compiled it with the kernel above 5.5 where the issue has been solved. If you need a tutorial, let me know. I already did it and it does not freeze. By the way Elementary OS does not use prefetch directory like Windows. It does not have the fast boot solution like Windows, so do not even compare totally different systems with totally different file system and without knowledge about systemd.

Anyway the example solution which solved issue in my case:

How to upgrade Elementary OS to the newest kernel. Only for braves.

Install necessary packages

sudo apt-get install build-essential libncurses-dev bison flex libssl-dev libelf-dev

To check hardware ####

sudo lspci

to check missing firmware

sudo update-initramfs -u

Make directories for firmware

mkdir /home/username/Downloads/kernel
mkdir /home/username/Downloads/amdgpu
mkdir /home/username/Downloads/i915
mkdir /home/username/Downloads/rtl

to get rid of missing firmware errors for amdgpu

cd /home/username/Downloads/amdgpu
wget https://github.com/M-Bab/linux-kernel-amdgpu-binaries/files/4124959/firmware-radeon-ucode-rock_2.110_all.deb.zip
unzip firmware-radeon-ucode-rock_2.110_all.deb.zip
sudo dpkg -i firmware-radeon-ucode-rock_2.110_all.deb

Or use eddy to install this deb

My comment: I was brave enough.

to get rid of missing firmware errors for i915

cd /home/username/Downloads/i915
git clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
sudo cp -R /linux-firmware/i915/* /lib/firmware/i915/

to get rid of missing firmware errors for rtl (Realtek LAN and Wi-Fi adapters in my DELL)

cd /home/username/Downloads/rtl
wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/rtl_nic/rtl8168fp-3.fw
wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/rtl_nic/rtl8125a-3.fw
sudo cp rtl8168fp-3.fw /lib/firmware/rtl_nic 
sudo cp rtl8125a-3.fw /lib/firmware/rtl_nic

Download kernel 5.7.0

cd /home/username/Downloads/kernel
wget https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.7.tar.xz
tar -xf linux-5.7.tar.xz
cd linux-5.7
cp -v /boot/config-$(uname -r) .config
make menuconfig 

save config and then exit.

use 4 core/thread - if your processor have 4 cores

make -j 4

or use 8 core/thread - if your processor have 8 cores

make -j 8

sudo make modules_install 
sudo make install 
sudo update-initramfs -c -k 5.7.0

ignore these errors below, just because those three bin files are not made yet

W: Possible missing firmware /lib/firmware/amdgpu/navi12_ta.bin for module amdgpu
W: Possible missing firmware /lib/firmware/amdgpu/navi10_mes.bin for module amdgpu
W: Possible missing firmware /lib/firmware/amdgpu/navi12_dmcu.bin for module amdgpu

sudo update-grub
sudo reboot
uname -mrs

to check errors after reboot:

sudo journalctl -b
sudo dmesg
