sysbench is a scriptable multi-threaded benchmark tool. 1


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

pakfire install sysbench


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
  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.


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.

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
