laravel eloquent performance PHP

I'm upgrading from an older version and I'm testing a new approach and I'm relatively new to this, so bear with me..... After upgrading to PHP 8.1 and Laravel 9.2, I've noticed that some Eloquent queries are taking significantly longer to execute than they did previously. For instance, a simple query to retrieve records from a large table is now taking upwards of 5 seconds, while it used to be around 200 milliseconds. I've tried enabling query logging and profiling to see if there's any specific scenario with the generated SQL queries, but they look fine. Here's a sample of the code I'm running: ```php $users = User::where('status', 'active')->orderBy('created_at', 'desc')->paginate(15); ``` I also checked my database indexes, and they seem to be in order. The table has around 100,000 rows, and I've confirmed that the database server is not under heavy load during these queries. Additionally, I've tested the same query directly in MySQL Workbench, and it executes almost instantly there. To further diagnose the question, I created a simple test route to see if the response was consistently slow: ```php Route::get('/test-users', function () { return User::where('status', 'active')->get(); }); ``` This endpoint is still slow. I've cleared the Laravel cache and even recompiled the classes, but it hasn't helped. I'm using MySQL 8.0 with Laravel’s default connection settings. Does anyone have insights into potential causes or configurations that may have changed with PHP 8.1 affecting Eloquent performance? Any help would be appreciated. My development environment is Ubuntu. How would you solve this? This is part of a larger API I'm building. Has anyone else encountered this? My development environment is Linux. This is my first time working with Php 3.10. Thanks in advance! This issue appeared after updating to Php 3.11.
