Using bzip2 to compare the relative performance of various computers

Summary:

The 1MB bzip2 benchmark

Just a simple benchmark to get a rough comparison of CPU power in various machines.

Technique

(Linux:)

1. Create a 1MB file of random data:

$ dd if=/dev/urandom of=/tmp/urandom bs=1M count=1

(for Mac, use bs=1m rather than bs=1M)

2. Time how long it takes to pipe the file through the bzip2 compression utilitiy:

$ time cat /tmp/urandom | bzip2 > /dev/null

(Run that a few times to ensure the random file is cached in RAM)

Results

Linksys NSLU2

The NSLU2 was a Linux-based home NAS-appliance from 2004.

266MHz ARMv5, 32MB RAM.
