+# PE4 Tuning
-# Background
+Tuning means to change some system variables/configurations (without changing the program itself) in order to optimize the performance.
-  *  Tuning means to change some system variables/configurations (without changing the program itself) in order to optimize the performance.
-# Aim
+## Learning Outcomes
-  *  Use subroutine profiling to focus the efforts on tuning specific procedures and improve the program's performance.
-# Outcomes
+* Analyze the IO performance of a program and tune it to increase performance.
-  *  Use profiling tools such as prof, gprof and line-by-line profilers.
