What it is

Quickbench is a free Bash script for measuring basic performance on Linux-based hosts, including virtual machines. It reports CPU configuration and runs busy-loop benchmarks at different parallel job counts, returning loop rates. Memory checks report Linux-allocatable memory and run a simple bandwidth test that may reflect L1 or L2 cache performance. Storage checks use parallel dd transfers with 4k and 1M blocks, reporting bandwidth and I/O rates. They run on the filesystem in the current working directory; to measure another device, mount its filesystem there and run Quickbench from that location. The script is designed for minimal Linux servers and needs no specific dependencies. It takes one parameter: the maximum duration in seconds for each benchmark loop. The project recommends at least 30 seconds for statistically meaningful results and cautions that values below 10 seconds may be unreliable. CPU loop measurements are not calibrated, so comparisons call for matching Quickbench, kernel, Bash, and dd versions. The project describes storage testing as non-thorough and says it cannot measure I/O completion latency. It is licensed under GPL-3.0.

Strong points and limits

Strong points

  • Free Bash script for Linux-based hosts.
  • Designed for minimal servers without specific dependencies.
  • Reports CPU, memory, and storage measurements.
  • Storage checks report bandwidth and I/O rates.
  • GPL-3.0 license.

Limits

  • Storage testing is described as non-thorough.
  • It cannot measure I/O completion latency.
  • CPU loop measurements are not calibrated.
  • Runs under 10 seconds may be unreliable.

Who it suits

Quickbench suits users who want a basic performance check on a Linux host or VM with a minimal server setup. It is less suited to people needing thorough storage testing or I/O completion latency measurements.

Verdict

Quickbench provides a basic CPU, memory, and storage snapshot through a single-parameter script. Treat results as limited: CPU loops are uncalibrated, and storage testing cannot measure completion latency.
