How to Measure Disk Performance with fio and IOPing

Disk performance testing is essential for understanding your storage capabilities. Tools like fio and IOPing help you evaluate IOPS, latency, and throughput. Let's explore how to use these tools effectively.

Introduction to Disk Performance Testing

Installation Commands: To begin testing, install both fio and IOPing

Installing fio and IOPing

– --rw=read: Sets the read-only test. – --bs=4k: Uses a 4k block size. – --numjobs=4: Runs 4 threads.

Running Basic fio Tests fio Test Example:

Random Access Example: To test random reads and writes, use the following command: – --rw=randrw: Mix of random reads and writes. – Provides a good representation of real-world scenarios.

Testing Random Read/Write with fio

IOPing for Latency Tests: IOPing works like ping, but for storage. To measure latency, run: ioping -c 10 /path/to/disk

Using IOPing to Measure Latency

Analyzing Results: fio: Look for IOPS, bandwidth, and latency metrics. IOPing: Focus on average and maximum latency values.
