# Benchmark
The `benchmark.py` script is used for testing OpenDHT in various cases. If you
run `benchmark.py --help`, you should find the following text:
optional arguments:
-h, --help show this help message and exit
--performance Launches performance benchmark test. Available args
for "-t" are: gets.
--data-persistence Launches data persistence benchmark test. Available
args for "-t" are: delete, replace, mult_time.
Available args for "-o" are : dump_str_log,
keep_alive, trigger, traffic_plot, op_plot. Use "-m"
to specify the number of producers on the DHT.Use "-e"
to specify the number of values to put on the DHT.
These options specify the feature to be tested. Each feature has its own tests.
You specify the test by using `-t` flag (see `benchmark.py --help` for full
help).
## Python dependencies
- pyroute2 >=0.6.9
- matplotlib
- GeoIP (used by `scanner.py` for drawing map of the world)
- ipaddress
- netifaces
- networkx
- numpy
## Usage
Before running the script, you have to build and install OpenDHT and its cython
wrapper (`cython3` has to be installed) on the system so that it can be found by
the benchmark script.
$ cd $OPENDHT_SRC_DIR
$ ./autogen.sh
$ ./configure
$ make && sudo make install
Then, you can use the script like so:
$ cd $OPENDHT_SRC_DIR/python/tools/
$ python3 benchmark.py --performance -t gets -n 2048
