High-Performance I/O Benchmark

This project provides a benchmark tool to compare the performance of different I/O engines for storage systems. The main goal is to evaluate how well each engine handles tasks like random read, random write, and mixed read-write operations in terms of IOPS, latency, and throughput.

Supported I/O Engines

• libaio: A traditional Linux asynchronous I/O library.
• io_uring: A newer, more efficient asynchronous I/O interface in Linux.
• SPDK (Storage Performance Development Kit): A user-space framework for high-performance I/O, designed especially for NVMe drives.

Features

• Compares I/O performance metrics: IOPS, Latency, and Bandwidth.
• Results are displayed in tables and charts for easy comparison.
• Allows testing with different thread configurations (1 thread and 4 threads).

How the Benchmarking Was Done

The tests were conducted using the following hardware configuration:

• CPU: 8-core Intel Xeon processor
• RAM: 32 GB
• Storage: NVMe SSD (Samsung 970 Pro)
• Test Duration: Each test lasted for 10 seconds
• Tool Used: fio (Flexible I/O Tester)

Key Performance Metrics

• IOPS (Input/Output Operations Per Second): Indicates the speed of I/O operations.
• Latency (µs): Measures the time taken to complete an I/O request.
• Bandwidth (MiB/s): Represents the data throughput during read/write operations.
