Middleware - Socket - Performance Evaluation

A simple socket project to evaluate the UDP and TCP performance. The client request a number and the server returns the respective fibonacci element. UDP and TCP implementations built in Go.

You can either check/run the code or run the tests to generate .csv files into your machine. Feel free to analyse the data any way you want.

To run the code

Prerequisites

• Go installed.

From Golang - Getting Started

Add /usr/local/go/bin to the PATH environment variable. You can do this by adding this line to your /etc/profile (for a system-wide installation) or $HOME/.profile:

$ export PATH=$PATH:/usr/local/go/bin

For convenience, add the workspace's bin subdirectory to your PATH:

$ export PATH=$PATH:$(go env GOPATH)/bin

Also a good idea add these lines:

$ export GOPATH=$(go env GOPATH);
$ export PATH=$PATH:$GOPATH/bin;

Install via go get

$ go get github.com/arma29/mid-socket-perf/socket/...

This command will build and install all go programs under mid-socket-perf/socket directory. It then installs that binaries to the workspace's bin directory as the folder name.

Usage

Now, you can run the program by typing its full path at the command line:

$ $GOPATH/bin/bin_name

Or, as you have added $GOPATH/bin to your PATH, just type the binary name:

$ bin_name

In this case, we need to start the server, and his respective client. Each server will listening to all net interfaces.

• UDP Server listening port: 1200
  • $ $GOPATH/bin/ServerUDP
• TCP Server listening port: 7171
  • $ $GOPATH/bin/ServerTCP

To run the clients, we need to pass the server IP and the request number as argument e.g:

$ $GOPATH/bin/ClientTCP 127.0.0.1 5
$ $GOPATH/bin/ClientUDP 127.0.0.1 5

This will print 10K lines containing the fibonacci number requested, sample number and the measured time between the request and response, in milliseconds.

To run the performance tests

Prerequisites

• Docker
• docker-compose

Usage

Simply run:

$ ./suit.sh

It takes 2-3 hours to run everything. Briefly, this will test the scenarios [UDP,TCP](socket type) x [1,2,3,4,5](simultaneous clients) and will output in /home/$USER/Output the .csv files in this format:

Fibonacci	Sample	Time
requested number	Sample number	RTT time
