Java servers benchmark

Why does it exist?

Dlya dopuska k zachetu.

Description

This is a simple application for testing different server' architectures:

• Blocking -- one thread for reading and one thread for writing for each client
• NonBlocking -- one selector for reading and one selector for writing for all clients
• Asynchronous -- asynchronous read/write

For all architectures, the common is that client tasks are executed in a thread pool of a fixed size.

For simplicity, all clients work in blocking mode.

Running

The main class is ru.mse.itmo.Main.

After running the main function you should choose parameters for benchmark. When the experiment is over, you will see the message Benchmark finished.

Results will be in the folder reports/ARCH_TYPE/. If you need plots you should run from the project root:

gnuplot reports/ARCH_TYPE/VAR_PARAMETER.p

where VAR_PARAMETER is the name of variable parameter (one of 'array_size', 'client_number', 'request_delta').

Values of the other parameters you can find near with the plot title.

If you want graphics for comparsion different architecturies you should run from reports folder:

python3 merger.py

You will see new plots in the reports folder.

Prerequisites

• Java (>= 15), gradle.7.1 for building and running
• gnuplot for plot generation
• python3 for more plots
