I am working on a new project to work and got confused by a strange problem when my application takes a long time to return the answer in both dev and prod. However, sometimes it returns a response very quickly. I read a few posts here about possible reasons why none of them solved my problems.
At first I thought it was because I had several sub requests, so I deleted them, but still had the same problems.
My average query is only 20-30 MB in DEV. I am trying to use a profiler to help me figure out where this might come from, however, each request shows that the longest part of the request will be a different area. For example, in one request the controller was the longest section, in another request on the same page it was a template listener, and the other was a security / firewall listener.
For example, a quick request on my home page takes about 116 ms. I am waiting for a min, updating and taking 9467 ms, or even saw that it takes 30,000 + ms.
While I can live with a little slowness in dev mode, prod does the same. Sometimes fast, sometimes slow. APC cache is enabled. Usually my doctrine requests take 4-20 ms to complete depending on the page.
I ran PHP 5.3, but decided to upgrade to 5.4 to see if this helped, but the same problems. I am using the latest stable build of nginx. PHP in FPM. The server works with other websites without problems - both with magento web applications and symfony 1.4 without any problems.
The server is a quad-core quad-core processor with 32 GB of RAM, so I have a lot of resources. Watching processes, when I make requests, I do not see abnormal CPU or memory loads.
I still need to try to run the application on another machine, but I don’t understand why all my other applications will work fine, and this is the only one who is experiencing such slowness. I will probably experience this tonight, but I wanted to see if anyone could experience such a problem before.
Here are some snapshots from my profiler when the request takes a long time:
Here are two when the request was fast as expected
This is my composer .json
