Stop Using p7zip: Why You Should Switch to 7zz on Linux

Still using p7zip on Linux? You’re working with software that hasn’t seen a significant update since 2016. While this community port served us well for years, the official 7-Zip for Linux has arrived—and it’s a game-changer.

The Problem: Stuck in 2016

Many package managers still default to p7zip version 16.02. This creates real problems:

• No Modern Instruction Sets: The aging codebase can’t leverage AES-NI, AVX2, or AVX-512—features your CPU has had for years.
• Compatibility Gaps: Archives created with newer compression methods? Good luck opening them.

The Solution: Meet 7zz

The official 7-Zip releases now include a standalone binary called 7zz. Everything is baked into one executable—no external dependencies, no path headaches.

Why It’s Faster

Switching from p7zip to 7zz delivers substantial performance gains on modern hardware:

1. Hardware Acceleration — Encryption and data operations now run at the silicon level using AES-NI and SIMD instructions.
2. Superior Multithreading — High-core-count CPUs finally get fully utilized.
3. Refined Algorithms — Years of micro-optimizations to LZMA/LZMA2 dictionary searches add up to real-world speed improvements.

How to Switch

If you’re using Pixi or Conda, install the modern 7zip package instead of p7zip. Then, use the standalone command:

# Avoid the legacy version
7z x archive.zip

# Use the modern standalone binary
7zz x archive.zip

Pro Tip: Keep Your Muscle Memory

Add an alias to your .bashrc or .zshrc, and keep typing 7z like you always have:

alias 7z='7zz'

See the Difference Yourself

Run the built-in benchmark to measure compression and decompression speeds on your hardware:

7zz b

Compare the results with your old p7zip installation. The numbers speak for themselves.
