performance-tools

A collection of performance-related tools and scripts

schedtime - A better time(1)-like tool

schedtime executes a program and prints the run time statistics. It works like the time(1) command, only instead of printing high-level details such as system and user time schedtime tells you whether the program was waiting on userspace (sleep(), wait()), waiting in the kernel (preemption, locking), or blocked on i/o (disk and network accesses).

pmucaps - Display Performance Monitoring Unit capabilities

PMU features vary from system to system, particularly in the cloud where it's common for the absolute bare minimum of hardware-events to be available. pmucaps prints which PMU capabilities are available on the current system and includes details such as microarchitecture, Last Branch Record support, and whether precise IPs can be reported with PEBS.
