Detailed explanation on comparative analysis of Laravel blog application performance under PHP7.0 and PHP5.6

The Homestead virtual machine version I currently installed is 2.1.8:

The PHP version pre-installed on this version of Homestead is 5.6.15:

We use the ab command (the performance testing tool provided by Apache) to test the performance of the Laravel application (taking the blog application developed using Laravel that we are currently talking about as an example) in this version. We simulate 10,000 times Requests, 100 concurrent stress tests:

ab -n 10000 -c 100 http://blog.app/

The running results are as follows:

What we want to focus on here is the red bold text, that is, the number of requests processed per second, which is the measurement system key indicators of performance. Depending on the system and hardware configuration, there will be some discrepancies in the data.

Now we will upgrade PHP in Homestead to version 7.0 as described in the section "Laravel Homestead supports PHP 7 ".

Use vagrant ssh to log in to the newly added homestead-7 virtual machine and check whether the PHP version information is correct:

At this time, access http in the browser ://blog.app will report an error because the newly installed Homestead database data is empty. You need to log in to the virtual machine and run the following command to run the migration and fill in the data:

php artisan migrate 
php artisan db:seed

It will be OK to visit again. Okay, let’s continue. Use the same ab command to perform a stress test:

ab -n 10000 -c 100 http://blog.app/

After comparison, the performance of the same Laravel application under PHP 7.0 is 54% higher than that under PHP 5.6. This is A very significant performance improvement. Of course, the data will vary depending on the environment, and there is still more room for improvement.
