What is I/O Performance?
I/O is an abbreviation for Input and Output Performance and means the read and write speed of your hard disk / virtual storage that provides writing files like source code of the generated business apps , pdfs, audio/media files etc, office documents etc.
Why I/O Performance is important
The Simplifier Application Editor generates a lot of small application source files, when you click on deploy to open your business app.
Thousands of small files should created and read again under one second to provide the App Builder a good User Experience and short waiting times.
That depends on a high I/O Performance from your installed virtual storage / nfs storage / hard disk.
Measurement of I/O Performance
To measure the underyling I/O Performance , we use the Linux Kernel Tools to get an reliable answer
