This would make our query more efficient, this is especially important since the products' table would presumably contain a body column of type TEXT which could be quite large. You can reduce the amount of data by selecting only the columns you need: public function index() While doing this might seem reasonable (we are even paginating the results!), there may be a lot of information in our products' table that we don't need for a listing page (body, category id, product type, etc).

'products' => Products::query()->paginate() Our controller would look something like this: public function index() Let's say for example that we have an e-commerce website, and we want to display a list of products. The more data there is the more time it will take, but that's not all, all that data has to be stored in memory for the lifetime of the request and that can cause your server to slow down and run out of memory under heavy loads.įortunately, in Laravel, we can specify exactly the data we need. When you make a query, the data that the database returns is sent over the network. One way we can optimize a query is by reducing the amount of data we fetch from the database. Here I some techniques that can improve your load times in your Laravel application.

Did you know that 1 in 4 visitors would abandon a website if it takes more than 4 seconds to load? While multiple factors can slow down a website, one common factor is inefficient database queries.Įloquent is a great tool that makes it easy to interact with the database in our Laravel applications, but sometimes we forget that what looks like a method call or property is running a database query under the hood, which might lead to slow page loads or high memory usage.
