The video presents an “ultimate performance hackers guide” with 15 Linux tweaks to make applications load faster and improve:

  • Responsiveness
  • Gaming performance
  • Network speed
  • Battery life

It covers RAM/CPU behavior, storage, kernel selection, desktop environment, power management, and system cleaning.

Key performance hacks / concepts (tech + product features)

  1. Preload (app preloading into RAM)

    • Runs in the background, learns frequently used apps, and preloads parts of them into memory to speed up future launches.

    • Install: bash sudo apt install preload

    • Logs: /var/log/preload.log

    • Best with 8GB+ RAM; gains can be less noticeable on very fast SSDs.
    • Remove: bash sudo apt remove preload

  2. Switch DNS to a faster resolver (Cloudflare / OpenDNS / Google DNS)

    • Speeds up website loading by reducing DNS resolution time before the page loads.
    • Steps: change IPv4/IPv6 DNS settings in network settings (example: Google DNS).
    • Re-enable Wi‑Fi after applying.

  3. Disable GNOME window animations / transitions

    • Removes UI animation delays when launching and switching windows.
    • Done via GNOME Tweaks or a command mentioned in the description.

  4. Prefer native .deb packages over Snap (reduce container overhead)

    • Snap apps are containerized, often duplicating dependencies and using more memory/disk reads.
    • Recommended approach: install via package repos / PPA, e.g.:
      • sudo apt install ...
      • install Synaptic
    • Notes: Flatpak may be faster than Snap, but native packages are generally best.

  5. Tune swap aggressiveness using vm.swappiness

    • Swap moves inactive RAM pages to disk, which can slow performance since disk is far slower than RAM.
    • Lower vm.swappiness reduces when swap is used.
    • Suggested values:
      • ~8GB RAM: reduce 60 → 40
      • 16GB+ RAM: keep around 30–20
    • Config edited in /etc/sysctl.conf (via command + edit instructions).

  6. Use the latest official GPU drivers

    • NVIDIA: install proprietary official drivers (not open-source) for larger performance/compat improvements.
    • Ubuntu typically installs via “Additional Drivers”; other distros (Fedora/Arch/Mint) may require manual steps.
    • AMD/Intel: drivers are usually included; keep the system updated.

  7. CPU power mode (GNOME / system “governors”)

    • Modes explained as CPU frequency governors:
      • Conservative / On-demand (efficiency)
      • Battery saver (lower clock speeds)
      • Performance (max frequencies; useful for gaming/video editing)
      • Balanced (dynamic scaling; recommended default)
    • Suggests using performance mode only for heavy workloads.

  8. Disable unnecessary auto-start apps / services

    • Apps/services starting at boot can add overhead.
    • Recommends using Stacer to manage auto-start items and services.
    • Caution: don’t remove critical messaging/system services.

  9. Advanced: switch to custom performance-tuned kernels

    • Stock kernel = balanced performance/stability.
    • Custom kernels tuned for:
      • desktop responsiveness
      • gaming / low latency
      • general performance
    • Examples mentioned:
      • XanMod
      • Liquorix
      • Zen Linux
    • Install process: add repos → update → install → reboot → select in GRUB.
    • Revert: boot into the old kernel first; uninstall custom kernel if needed.
    • Risks: kernel-level changes can cause driver issues or random bugs.

  10. Reduce display refresh rate on battery (e.g., 144Hz → 60Hz)

    • High refresh rates increase GPU workload and power drain.
    • Lower refresh rate reduces graphics subsystem activity and saves battery.
    • Switch back to higher rate for gaming.

  11. TLP for automatic power management (battery optimization)

    • Installs TLP to autotune battery-related settings.
    • On battery: switches CPU governor, powers down Wi‑Fi/Bluetooth when unused, tunes disk power modes, autosuspends USB, etc.
    • Reported effects: quieter fans and cooler laptop temps.

  12. Feral GameMode for gaming “turbo”

    • Open-source tool from Feral Interactive.
    • Boosts system settings while a supported game runs:
      • CPU governor → performance
      • process priority / I/O priority adjustments
      • disable screen saver
      • request GPU performance mode
      • suppress competing background processes
    • Mentioned as often available by default on Ubuntu; Steam games may trigger it automatically.
    • Can be forced via launch options or run prefix for non-Steam apps.

  13. ZRAM (compressed swap in RAM)

    • Uses compressed swap inside RAM.
    • Claims an effective 20–25% increase in usable memory.

    • Install (as described in subtitles): bash sudo apt update sudo install ztools

    • Mentions optional configuration via /etc/tc/default/zram and checking status after reboot.

  14. Use a lightweight desktop environment

    • If GNOME feels heavy, switch to XFCE, MATE, or LXQt.
    • Benefits: lower RAM/CPU use, fewer animations/effects, lighter default apps/background services.
    • Tradeoff: less “bells and whistles.”

  15. Clean system with BleachBit

    • Uses BleachBit to remove caches, temporary files, old logs, and junk.

    • Install: bash sudo apt install bleachbit

    • Approach described:

      • run as root for system cleanup (be cautious with dangerous options)
      • run without root afterward for application cache cleanup
    • Suggested cadence: every ~6 months; claimed to free multiple GBs and improve responsiveness.
