Performance-Test-Program
A small program that acts as a C profiler.
Simple Performance Test
Description
This is a simple program in C for performance testing which only works for x86 and x86_64 systems. A for loop is executed x times and we use the Assembly instruction rdtsc for profiling.
Test 1
Test #1 simply creates a character array with a size of 256 bytes and a string value of "a string" is copied to the character array via strcpy(). Afterwards, a variable representing the profiling average along with the highest and lowest profile speeds are calculated.
Command Line
There is currently only one command line argument which may be found below.
-c --count => The amount of times to execute for/while loops.
Example
./perftest1 -c 10000000
Building And Installing
You can use git and make to build and install the program.
git clone https://github.com/gamemann/Performance-Test-Program.git
cd Performance-Test-Program/
sudo make && sudo make install
The binary perftest1 will be copied to /usr/bin. Therefore, it should be added to your path (e.g. you can write perftest1 ...).
