How to do performance testing for PHP7

After we test the performance of PHP7 with some simple loop programs, will the focus shift to PHP applications? There is such a question, PHP7's performance has indeed exploded, but when our application is really run with PHP7, will the performance also improve so much?

#A big event has happened in the IT world these days, that is, PHP has released the latest version, and PHP7 finally meets phper.

Many programmers who pay attention to PHP must have browsed various forums in the past two days and read all the major posts. They know that the biggest breakthrough of PHP7 this time is the performance improvement, which is known as 100%! From the test data given by various experts, we can also see that it may be far from this number, much higher than the conservative estimate of 100%. So the question is, after we test the performance of PHP7 with some simple loop programs, will the focus shift to PHP applications? There is such a question, PHP7's performance has indeed exploded, but when our application is really run with PHP7, will the performance also improve so much?

I want to tell you that’s not the case! why? How was it tested? Maybe you are about to ask, but now I want to tell you that we can actually do these things with the help of some mature application performance testing products. I know that the performance of PHP7 has been improved, but the performance of the application I want to run on PHP7 is also equally high. I need to see it clearly, so here is the tool: I have used some relatively good products, and I will share them with you. Recommended:

1. XHprof

Those who have learned about performance monitoring must be familiar with XHprof. xhprof - an extension developed by Facebook to test PHP performance. This is the entire explanation given by the open source Chinese community. It is one sentence but very awesome. Because it was developed by Facebook, it is naturally not bad. But from the same perspective, because it was developed by Facebook, its deployment difficulty and technical requirements are naturally not low. Anyone who has tried it must know it. And because of Facebook's huge amount of data, the data displayed to us by this tool is not that accurate and the display method is indeed not very friendly. Although I am a programmer, I can only say that after watching it for a long time, I felt it was too stiff.

2. Blackfire

Blackfire Profiler Fire up your PHP App Performance translates to clearly display your application performance. This tool is very powerful, really powerful. It is an application performance monitoring tool specially made for PHP applications. Because it is specially used to monitor PHP applications, it has achieved all aspects of the monitoring functions of PHP applications. The most important problem is that I have only seen their product demos on the official website and have never used their products. It's not that I don't want to, but I really can't do anything. I have deployed it countless times and searched through the problem-solving documents on the official website, but I have not been able to successfully deploy this tool. In the end, I was defeated and could only find a product that was easy to deploy and equally powerful.

3、OneAPM

Sometimes some products are right in front of you, but you just don’t find them. After you see them and use them for a while, you will find that maybe this is the product you have always wanted. That's right, it's OneAPM. You may think that I am saying this and praising him is a bit too much. Well, let me tell you how long it took me from seeing OneAPM to seeing my application performance data - 7 minutes. That's right, it only took 14 minutes from download and installation to the various performance data I saw (response time, throughput, etc.). It’s not very short, but I spent nearly two days on XHprof. The leader of blackfire saw this tool at the time and asked me to write a test report. I worked on it for 3 days but failed to deploy it successfully. In the end, thanks to the leader’s understanding, he tried it. It seemed that in the end Let's just leave it alone. I don't need to tell you what the result will be! And in terms of performance data, I think OneAPM is not much different from those two, but OneAPM's functions are more powerful: reports, error messages, server status, slow transaction tracking, etc., all make me feel bright.
