How to improve ubuntu performamce

 Here I have involved some steps which may helpful to optimize your Ubuntu server speed.

 

1. Update Your System

Regularly update your system to ensure you have the latest performance improvements and security patches.

 sudo apt update

sudo apt upgrade

 2. Remove Unnecessary Start-up Applications

 Disable unnecessary startup applications to reduce boot time and free up system resources.

 sudo apt install gnome-tweak-tool

gnome-tweaks

 Navigate to the "Startup Applications" section and disable unnecessary programs.

 3. Use Lighter Desktop Environments

If you are using a resource-heavy desktop environment like GNOME or KDE, consider switching to a lighter one like XFCE or LXDE.

 sudo apt install xfce4

sudo apt install lxde

 4. Manage Swappiness

Adjust the swappiness value to reduce the use of the swap file and improve performance.

 sudo sysctl vm.swappiness=10

sudo nano /etc/sysctl.conf

Add or edit the line vm.swappiness=10 in /etc/sysctl.conf.

 5. Clean Up Your System

Remove unnecessary files and packages to free up space and reduce clutter.

 sudo apt autoremove

sudo apt clean

sudo apt autoclean

 Use a tool like BleachBit to clean up system files.

 sudo apt install bleachbit

sudo bleachbit

 6. Optimize Disk Usage

Use tools like fsck to check and repair file system errors.

 sudo fsck /dev/sdX

Use fstrim to trim SSDs.

sudo fstrim -v /

 7. Use a Faster DNS Server

Changing your DNS server can improve network performance. Consider using a faster DNS provider like Google DNS or OpenDNS.

 sudo nano /etc/resolv.conf

Add the following lines:

 nameserver 8.8.8.8

nameserver 8.8.4.4

8. Upgrade Hardware

Adding more RAM or upgrading to an SSD can significantly improve system performance.

9. Disable Animations

Disabling animations can make your desktop environment feel snappier.

gsettings set org.gnome.desktop.interface 

enable-animations false

10. Monitor System Resources

Use system monitoring tools to keep an eye on resource usage and identify bottlenecks.

 sudo apt install htop

htop

 11. Use Lightweight Applications

Use lightweight alternatives to resource-heavy applications (e.g., using Featherpad instead of Gedit).

 12. Kernel Optimization

 Use a low-latency kernel if you're doing audio production or other real-time tasks.

 sudo apt install linux-lowlatency
