sysbench

sysbench is a scriptable multi-threaded benchmark tool. 1

Installation

sysbench can be installed with the Pakfire web interface or via the console:

pakfire install sysbench

Usage

There is no web interface for this Addon. To run this Addon open the client console or terminal and access the IPFire box via SSH.

To obtain a list of possible options:
sysbench --help

The output is similar to this:

[root@ipfire ~]# sysbench --help
Usage:
  sysbench [general-options]... --test=<test-name> [test-options]... command
. . .
Compiled-in tests:
fileio - File I/O test
cpu - CPU performance test
memory - Memory functions speed test
threads - Threads subsystem performance test
mutex - Mutex performance test
oltp - OLTP test
. . .
See 'sysbench --test=<name> help' for a list of options for each test.

Examples

CPU Benchmark

Benchmark CPU performance as follows:

sysbench --test=cpu --cpu-max-prime=20000 run

Look for Test execution summary - total time. Example:

total time:                          54.9157s

Memory Benchmark

Read memory performance:

sysbench --test=memory --memory-block-size=1K --memory-scope=global --memory-total-size=100G --memory-oper=read run

Write memory performance:

sysbench --test=memory --memory-block-size=1K --memory-scope=global --memory-total-size=100G --memory-oper=write run

Look for the operations per second and throughput.
Example:

Operations performed: 104857600 (1208603.66 ops/sec)
102400.00 MB transferred (1180.28 MB/sec)

File IO Benchmark

Measure file IO performance:

#  create a temp directory on a partition that has available space
cd $(mktemp -d /var/tmp/tmp.XXXXXXXXX)

#  create a test file larger (much larger) than the total amount of RAM
sysbench --test=fileio --file-total-size=10G prepare

#  now run the benchmark!
sysbench --test=fileio --file-total-size=10G --file-test-mode=rndrw --init-rng=on --max-time=300 --max-requests=0 run

#  Finally delete the test files from the temp directory
sysbench --test=fileio cleanup

Do you see this error FATAL: Failed to write file! errno = 28? Then there is no space left in the current partition. Run the above command cd $(mktemp -d /var/tmp/tmp.XXXXXXXXX).

[root@ipfire ~]# cd $(mktemp -d /var/tmp/tmp.XXXXXXXXX)

[root@ipfire ~]# sysbench --test=fileio --file-total-size=10G prepare
