How to optimize Yii2?

Question

Yii

Now the page loads in 0.73-0.88s, I debugged all requests + the template output time takes 0.2-0.3 seconds, which takes the rest of the time I can’t understand ... I calculated the execution time of all requests in Yii::getLogger()->getProfiling() takes 0.07 with

Answer 1

in this case, if you are sure that the database queries are optimized, and the loading time still does not suit you, you can still try these options.
1) http-cache
2) Get away from using ActiveDataProvider (unless of course you have it on this page) towards ArrayDataProvider. At one time, this helped me a lot when it was necessary, at the request of the customer, to display 500 items in the list on one page. ActiveDataProvider ate a lot of memory and time to create objects and access its methods and properties. On arrays, everything began to fly three times faster ...

Answer 2

The page loading speed depends not only on how fast the server processes the request, but also on many other factors, such as the size of the uploaded images, the size of styles and scripts, DNS record recognition, etc.
Here is a small overview of the points that affect page loading speed

Answer 3

In addition to the previous answers: we must not forget about setting up the server - what is under your hood - nginx + php-fpm will not give such a delay, but apache + php_mod may well.
It is rather reckless to count the execution time only for queries to the database - php can also eat up quite a lot, not the fastest language.
Especially in the context of profiling, debugging - at the same time, Yii writes, collects and writes a huge amount of information to disk, if you disable YII_DEBUG, everything is possible and flies.
It can also slow down due to XDebug if it is enabled by default.
Well, it is unnecessary to forget that the speed of return is not a constant concept. And if on your virtual machine on the dev-machine it is 0.3, then on a normal server it may well be 0.1

2. XHProf helps bottlenecks very well

Answer 5

Loading statics, for example. The higher the ping value, the longer it will take to load.
