Storage latency is one of the most impactful things on the performance and responsiveness of your Linux environment. If your environment experiences a high latency, then you get I/O waits and slow speed of the read and write operations. The result is overall performance problems and slow speed of the whole virtualization or I/O intensive applications.

Monitoring of your storage latency helps you to track the cause of latency and identify fast any bottlenecks causing performance issues. Troubleshooting of Linux latency was never so easy!
