NAME ^

Benchmark::Object - Simple interface to do benchmarking.

SYNOPSIS ^

    use Benchmark::Object;

    print "Benchmarking for loop runs 2000 times.\n";
    #Sart benchmarking here
    my $obj = Benchmark::Object->start();
    
    for(my $i = 0; $i < 2000; $i++) {
    }
    
    #First pause
    $obj->pause();
    
    print "Benchmarking for loop runs 1000 times.\n";
    #First resume
    $obj->resume();
    
    for(my $i = 0; $i < 1000; $i++) {
    }
    
    #Second pause
    $obj->pause();
    
    print "Benchmarking for loop runs 500 times.\n";
    #Second resume
    $obj->resume();
    
    for(my $i = 0; $i < 1000; $i++) {
    }
    
    #Final stop of benchmarking
    $obj->stop();
    
    #Print total result in tabluar form
    $obj->print_benchmark();
    
    #Get benchmark result on return hash form
    my $ret = $obj->get_benchmark();
    require Data::Dumper;
    print Data::Dumper::Dumper($ret);

DESCRIPTION ^

This is a simple benchmarking module, can be used to get the banchmark at any part of code or complete code.

There are four functions (start(it is also constructor), pause, resume, stop) in this module to perform benchmarking. It is recommended to use these functions in logical order. otherwise total benchmarking result will be having incorrect value.

There are two fundtions, (print_benchmark and get_benchmark) to get result of benchmark.

start

This function will start benchmarking.

pause

This function will pause benchmarking. Should be called after start or resume.

resume

This function will resume benchmarking, which was paused earlier using pause() function. Should be called after pause.

stop

This function will stop benchmarking. Should be called after start or resume.

print_benchmark

This function will print benchmark result in tablur form. Below is example:

    Start Datetime: Oct 14 2013 15:27:36
    End Datetime: Oct 14 2013 15:27:36
    Iteration                         Second         Microsecond    Total in Microseconds

    PAUSE0                        1381744656              838417            1.381745e+015

    END                           1381744656              838851            1.381745e+015

get_benchmark

This function will return anonymous hash reference of benchmark result. Below is an example:

    {
        'START_DATETIME' => 'Oct 14 2013 15:27:36',
        'PAUSECOUNT' => 2,
        'TAKEN_MICROSEC' => 798,
        'PAUSE2' => {},
        'RESUMECOUNT' => 2,
        'END_MICROSEC' => 838851,
        'RESUME0' => {
                    'START_SEC' => 1381744656,
                    'START_MICROSEC' => 838435
                    },
        'PAUSE0' => {
                    'START_SEC' => 1381744656,
                    'START_MICROSEC' => 838417
                    },
        'END_SEC' => 1381744656,
        'TAKEN_SEC' => '0',
        'END_DATETIME' => 'Oct 14 2013 15:27:36',
        'START_SEC' => 1381744656,
        'PAUSE1' => {
                    'START_SEC' => 1381744656,
                    'START_MICROSEC' => 838640
                    },
        'RESUME1' => {
                    'START_SEC' => 1381744656,
                    'START_MICROSEC' => 838651
                    },
        'START_MICROSEC' => 838024
    }
