It is a multi-purpose benchmark that features tests for CPU, memory, I/O, and database performance testing. [3] It is a basic command line utility that offers a direct way to benchmark computer hardware. It now comes packaged in most major Linux distribution repositories such as Debian, Ubuntu, CentOS and Arch Linux. [4]
BogoMips (from "bogus" and MIPS) is a crude measurement of CPU speed made by the Linux kernel when it boots to calibrate an internal busy-loop. [1] An often-quoted definition of the term is "the number of million times per second a processor can do absolutely nothing".
time (Unix) - can be used to determine the run time of a program, separately counting user time vs. system time, and CPU time vs. clock time. [1] timem (Unix) - can be used to determine the wall-clock time, CPU time, and CPU utilization similar to time (Unix) but supports numerous extensions.

The relevant term is of the porting target is computer architecture; it comprises the instruction set(s) and the microarchitecture(s) of the processor(s), at least of the CPU. The target also comprises the "system design" of the entire system, be it a supercomputer, a desktop computer or some SoC, e.g. in case some unique bus is being used.
Inquisitor is a software suite used for hardware diagnostics, stress testing, certification and benchmarking platform.It is available in three formats: Standalone – As a package to be installed into existing Linux installation; such practice is somewhat limited in available tests.
The interface between the perf utility and the kernel consists of only one syscall and is done via a file descriptor and a mapped memory region. [6] Unlike LTTng or older versions of oprofile, no service daemons are needed, as most functionality is integrated into the kernel.
cgroups (abbreviated from control groups) is a Linux kernel feature that limits, accounts for, and isolates the resource usage (CPU, memory, disk I/O, etc. [1]) of a collection of processes. Engineers at Google started the work on this feature in 2006 under the name "process containers". [2]
