Quickbench
What it is
Quickbench is a free Bash script for assessing the basic performance of Linux-based hosts, including virtual machines. It reports CPU configuration and runs a busy-loop benchmark at different parallel job counts, returning loop rates. It also reports allocatable memory and runs a simple bandwidth test, which may reflect L1 or L2 cache performance. Storage checks run parallel transfers with 4k and 1M blocks and report bandwidth and I/O rates. They operate on the filesystem in the current working directory; to check another device, mount a filesystem there and run the script from that mount point. Quickbench is designed for minimal Linux servers without specific dependencies. It accepts one parameter, the maximum duration in seconds for each benchmark loop. The project recommends at least 30 seconds for meaningful results and cautions that runs below 10 seconds may be unreliable. CPU measurements are not calibrated, and the storage test is not thorough and cannot measure I/O completion latency. Quickbench is licensed under GPL-3.0.
For and against
For
- Free Bash script with no specific dependencies
- Reports CPU, memory, and storage results
- Supports multiple CPU job counts
- Storage checks use parallel 4k and 1M transfers
Against
- Linux only
- CPU loop measurements are not calibrated
- Storage test cannot measure I/O completion latency
- Runs below 10 seconds may be unreliable
The verdict
Quickbench provides a basic set of host measurements in a small Linux script. Its results have limits, particularly for CPU comparisons and storage latency.
Who it suits
It suits people seeking a quick performance check of a Linux-based host or VM. Users comparing machines should match Quickbench, kernel, Bash, and dd versions.
