We are currently trying to improve one of our project's performance and therefor I try to understand factors that influence a page's rendering time and memory consumption.
Before optimizing complex pages with element queries I want to optimize a minimalistic twig template without any element query. This is the template:
<html> <head> <title>Testing</title> </head> <body> <h1>Testing</h1> {% if craft.app.config.general.devMode %} <p>Dev Mode is <strong>enabled</strong>.</p> {% else %} <p>Dev Mode is <strong>disabled</strong>.</p> {% endif %} {% if craft.app.config.general.enableTemplateCaching %} <p>Template Caching is <strong>enabled</strong>.</p> {% else %} <p>Template Caching is <strong>disabled</strong>.</p> {% endif %} </body> </html> I put the template into the templates/ folder and call it directly.
I tried this on 3 different projects in production and enabled the frontend debug toolbar for my user. All 3 projects have almost the same setup: PHP Version (8.2), Craft Version (4.15.0.2), same machine, there are only differences in plugins, sections/entrytypes/entries and some minor module differences.
Interestingly I received 3 different results for the 3 projects:
- 50ms rendering time and 1,5MB mem consumption
- 65ms and 5MB
- 180ms and 20MB
Next I cloned the slowest project to a second instance on the same machine and:
- one after the other disabled all plugins: (almost) no change in rendering time and memory
- removed all modules: no effects
- removed almost all elements using the console command
elements/delete-all-of-type: nothing - cleared all caches: nothing
- did garbage collections: nothing
To be honest: I do not understand it. It's like Craft ignores my wishes to get a better understanding:
Do you have any other ideas? Or give me a hint on what is actually influencing rendering time and memory consumption?
