network_ping_test

How to build:

Install:

• g++
• python3.5, python3.5-dev
• python3.5-gevent
• uvloop
• golang 1.7+

For ubuntu 14.04:

$ sudo add-apt-repository ppa:fkrull/deadsnakes
$ sudo apt-get update
$ sudo apt-get install python3.5 python3.5-dev g++ make
$ wget https://bootstrap.pypa.io/get-pip.py
$ sudo python3.5 get-pip.py
$ sudo python3.5 -m pip install uvloop gevent

install golang

Disable CPU throttling:

$ sudo apt-get install cpufrequtils
$ sudo cpufreq-set -r -g performance
$ cpufreq-info     # << CHECK OUTPUT!

Clone code:

$ git clone https://github.com/koder-ua/network_ping_test.git

Compile all:

$ cd network_ping_test
$ make

How to run:

Server:

# ulimit -n 65536
# echo 1024 65535 | tee /proc/sys/net/ipv4/ip_local_port_range
# taskset -c .... ./bin/server_cpp

Client:

# ulimit -n 65536
# echo 1024 65535 | tee /proc/sys/net/ipv4/ip_local_port_range
# taskset -c SOME_CPU_CORE_NUM python3.5 main.py SERVER_IP WORKER_COUNT TESTS_NAMES_OR_*

On single-node test be carefull to run client and server on different HW cores (not only on different logical cores, as two logical cores == one hardware in case of HT)

where test names is coma separated name of test.

To get all available tests execute

$ python3.5 main.py --list

Visualize

Visualization code is in plot_tests_results.py, but it doesn't support passing parameters from CLI - you need to change a code, to get other results. Also it requires texttable and mathplotlib modules.
