Performance Comparison of Buffering Strategies in Java

Description

This project compares the performance of different buffering strategies in Java. The strategies are:

• FileChannel with indirect buffers
• FileChannel with direct buffers
• FileChannel using the transferTo() operation
• Buffered I/O Stream
• Stream read into a byte array managed by the programmer

The results are presented in the following table:

Type of buffering	SmallFile and Buffer = 1024	BigFile and Buffer = 1024	SmallFile and Buffer = 65536	BigFile and Buffer = 65536
FileChannel with indirect buffers	30 ms	84 ms	14 ms	17 ms
FileChannel with direct buffers	2 ms	32 ms	2 ms	6 ms
FileChannel using the transferTo() operation	6 ms	27 ms	0 ms	31 ms
Buffered I/O Stream	0 ms	14 ms	44 ms	46 ms
Stream read into a byte array managed by the programmer	9 ms	18 ms	5 ms	0 ms

How to run

The project is a Java Project. To run it, you need to have Java installed on your machine. After that, you can run the project by opening a terminal in the directory and executing the following commands depending on your operating system:

Mac/Linux Give the permission to execute the script (only the first time):

chmod +x exec.sh

and then execute it:

./exec.sh

Windows Just execute it:

.\exec.bat
