HumHub utility module for creating test data and performance profiling

HumHub Profiler

⚠ Do not install this module on a production environment!

This HumHub module can be used to emulate an active HumHub network with a certain amount of users, spaces and content. This module uses yii faker library in order to generate partly random test data.

You can furthermore use this module for profiling purposes.

Fixtures

Users

• First user with id 1 is always in admin group with name root
• Other usernames are of format User, so user with id 2 has username User1
• All user passwords are test
• By default 2000 Users will be created

Spaces

• Space names are random
• Users will be spread in steps of 100 through the first spaces
• By default 2000 Spaces will be created

Content

• This module will generate post and related content created activities
• The content is spread through the first few spaces and profile of user1
• By default 80000 content entries will be created (50/50 Activity/Post)

Following

• By default User 1 has 1000 followers
• By default the first few spaces

Friends

• By default User 1 has 1000 friends

Generate fixture data

Generate all:

php yii profiler/fixture/generate-all

Generate specific fixture:

php yii profiler/fixture/generate content/content

Load fixture data

⚠ This will overwrite existing data in your database!

Load all:

php yii profiler/fixture/load "*"

Note: The execution of this command may take some time...

Load specific fixture:

php yii profiler/fixture/load "Content"

Profiling

Its recommend to set SET GLOBAL query_cache_size = 0; in your test mysql db in order to test against non cached query times.

SHOW VARIABLES LIKE 'query_cache_size'; should return a value of 0.

Run profiler

Run stream profiler with default run count:

php yii profiler/stream/run

Set run count:

php yii profiler/stream/run --count=200

Implement custom profiler

class MyProfilerController extends ProfileController
{
    public function actionRun()
    {
       $result = $this->runProfiler(function(ProfilerResult $result) {
            // DO SOME WORK YOU WANT TO PROFILE
        }, $this->title);

        $this->printResult($result);
    }
}
