Intro to IO Profiling of Applications
Posted on Wednesday, March 10, 2010 @ 17:37:10 CET
Topic: HOWTOs and similar articles

One of the classic problems in designing storage solutions is that we don’t know what kind of IO performance applications need. We may have some empirical knowledge, “switching to SSD’s improved by wall clock time by 25%,” or, “adding an extra drive improved my application performance by 11%.” While this information is helpful to some degree what is missing is the understanding of why performance improved and by extension, what are the driving mechanisms behind the performance improvement. Perhaps equally important for the application developers is that understanding the driving forces of IO performance for your application can be used to improve the IO performance, if needed.
