linux default iconkernbench Publisher's description

kernbench is a CPU throughput benchmark.

This is a cpu throughput benchmark originally devised and used by Martin J. Bligh. It is designed to compare kernels on the same machine, or to compare hardware. To compare hardware you need to be running the same architecture machines (eg i386) and run kernbench on the same kernel source tree.

kernbench runs a kernel at various numbers of concurrent jobs: 1/2 number of cpus, optimal (default is 4xnumber of cpus) and maximal job count. Optionally it can also run single threaded. It then prints out a number of useful statistics for the average of each group of runs.

You need at least 2Gb of ram for this to be a true throughput benchmark or else you will get swapstorms.

Ideally it should be run in single user mode on a non-journalled filesystem. To compare results it should always be run in the same kernel tree.

What's New in This Release:

??? Incorrect counting of CPUs was fixed.
??? The -j option was changed to at least 4GB ram.

System Requirements:

No special requirements.
Program Release Status: Minor Update
