How to optimize performance in Laravel8? Optimization Tips Sharing

This guide lists various performance optimization tips, from quick optimizations to in-depth tuning, that can help build high-performance Laravel applications.

There are many students onEnlightnwho helped us write this guide. If you are looking for Laravel automation performance or security tools, you may wish to visit this website.

Why improve performance?

There is no doubt that users prefer faster apps to slower ones. .

According to a study by Google, 53% of users on mobile terminals will lose (choose to leave) if a website takes more than 3 seconds to load. And the average loading time for a mobile website is about 15 seconds. This is why performance matters!

Every additional second your app takes to load, the lower your customer conversion rate will be. Fortunately, for Laravel applications, this is not a difficult problem to solve.

1. Use built-in performance capabilities to win quickly

Laravel has some built-in performance improvement features that can be used with a simple configuration.

The most critical performance improvement isRoute cache. Did you know that every time your Laravel application is launched, the middleware is determined, aliases are resolved, route groups are resolved, route controller actions are specified, and request parameters are processed?

You can use the Artisan commandroute:cacheto cache all required routing information, thereby skipping route processing:

php artisan route:cache

This command can give you 5 times Performance improvements! It is the simplest and most effective optimization.

In addition to route caching, Laravel also provides the following:

• Configuration cacheSkips.envandconfigParsing of files.
• View CachingPrecompile your Blade template views.
• Event CacheCache the list of all events and listeners in the application.

Tip: You should make sure to add the above cache command to your deployment script so that it is re-cached every time you deploy. Otherwise, any changes to routing or configuration files will not be reflected in the app.

2. Optimize Composer

A common mistake made by Laravel developers is to install all dependencies in production mode. Some development packages, such as Ignition, record queries, logs, and dumps in memory, providing friendly error messages with context and simplifying debugging. While this is useful in development, it can slow down your application in production.

In the deployment script, when using Composer to install the expansion package, be sure to use the-no-devoption:

composer install --prefer-dist --no-dev -o

In addition, please ensure that in the production environment as mentioned above Use the-ooption. This allows Composer to optimize the autoloader by generating "classmaps".

If your application does not generate classes at runtime, you may choose to use the--classmap-authoritativeoption instead of the-ooption for further optimization. Be sure to check out the Autoloader's Composer documentationOptimization strategies.

3. Choose the right driver

Choose the right driver Caches, queues, and session drivers can have a huge impact on application performance.

For caching in production environments, memory cache drivers such as Redis, Memcached or DynamoDB are recommended. You might consider using local filesystem caching for a single-server setup, although this will be slower than the cache-to-memory option.

For queues, it is recommended to use the Redis, SQS or Beanstalkd driver. The database queue driver is not suitable for production environments and is known to have deadlock issues.

For Session, database, Redis, Memcached or DynamoDB driver is recommended. The cookie driver has file size and security restrictions and is not recommended for production environments.

4. Process time-consuming tasks through the queue

In a typical web request process, there may be some specific tasks that require a lot of time. It takes a long time to complete. Laravel has a first-class queue system, which allows us to transfer time-consuming tasks to queued tasks, allowing your application to respond to requests extremely quickly.

In general, common examples of such tasks include parsing and storing CSV files, interacting with third-party APIs, sending notifications to users, long and time-consuming database queries, and search index updates.

5. Text file settings HTTP compression headers

Compression headers can have a significant impact on application performance. Make sure you enable compression or CDN on your web server for text format files such as CSS, JS, XML, or JSON.

Image formats already have compression algorithms implemented and in most cases image format files have been compressed, and images are not text format files (except for SVG format, which is an XML document). Therefore, the image format does not require compression.

You can set up gzip or brotli (older browsers may not support brotli) on your web server or CDN to get a big performance boost.

Normally, compression can reduce file size by about 80%!

6. Set HTTP cache headers on static resources

Caching can improve the performance of your application, especially for static resources, such as Images, CSS and JS files. It is recommended to enable cache control headers at the web server or CDN level, if applicable. If you wish to set these control headers on the Larvel application instead of the WebServer, you can use Larvel'sCache Control Middleware.

The Cache header field ensures that the browser does not repeatedly request static resources when visiting the website multiple times. This improves the user experience as the website loads faster on subsequent visits.

Laravel Mix providescache cleaningfunctionality out of the box so that when CSS or JS code is changed, the browser does not continue to use old cached content.

7. Use CDN services to accelerate static resources

A content delivery network (CDN) is a geographically distributed server group that uses Servers closer to website visitors are provided. This allows users to experience faster loading times.

In addition to faster loading speeds and shorter loading times, CDN also has other advantages, such as reducing web server load, DDOS protection and analysis of static resource services, etc.

Some popular CDNs include CloudFlare, AWS CloudFront, and Azure CDN. Most CDNs have a certain free trial limit. Consider using a CDN to improve static resource loading performance.

Laravel provides out-of-the-box CDN support componentsMixand helper functionsassetin the framework.

8. Minimize JS and CSS code

Minimizing scripts will remove unnecessary overhead from your application Code (such as code comments, whitespace, shortened variable names, and other optimizations). This is a common and effective way to reduce the size of JS and CSS files in production environments.

9. Use cache wisely

Laravel has built-incachingsupport. Caching is best used for read-heavy workloads. These workloads often involve time-consuming data retrieval or data processing tasks.

Some common scenarios for caching may include:

• Caching static pages: Caching static pages is a piece of cake. Laravel’s official website usesPage CacheCache each document page.
• Fragment or partial caching: Sometimes it may be more useful to cache a fragment of a page rather than caching the entire page. For example, you might want to cache a page header that contains the username and user avatar. You can cache the page header fragment once without having to fetch the data from the database each time.
• Query Cache: Query cache may be useful if your application frequently queries the database for items that rarely change. For example, when you run an e-commerce website, you may want to cache the item categories displayed on the mall's homepage instead of reading these item categories from the database each time you visit the mall.

Keep in mind that caching is not useful forlong tail(items that are rarely requested). On the contrary, it should be used with caution for any frequent data retrieval (as compared to data updates).

You must also ensure that the cache is invalidated or flushed every time the cached content changes. For example, if you are caching profile headers, refresh the cache after a user updates their profile picture.

10. Identify your application’s performance bottlenecks

If some of your pages take longer to load or have higher memory usage , you may need to identify performance bottlenecks. There are many tools in the Laravel ecosystem to help you do this, including Laravel Telescope, Laravel Debugbar, and Clockwork.

Some common performance bottlenecks include:

• N 1 query: If your code executes one query for each record, it will result in more Network round-trips and more queries. This can be done in Laravel usingData preloading.
• Duplicate requests: If your code executes the same query multiple times while handling the same request, it may slow you down The speed at which the application runs. Typically, if multiple services or classes require the same data set, these issues can be solved by extracting data calculations or retrievals into separate classes.
• High memory usage: In order to reduce the memory usage of the application, you can consider usingLazy collectionsandQuery chunkingto reduce the single The volume of data processed. To store files, useAutomatic streamingto reduce memory usage.
• Slow Query: If the query execution takes too long, you should consider using the query cache and/or use theEXPLAINstatement to optimize the query execution plan.

If you are unable to identify performance bottlenecks in your application using the above debugging tools, you may consider using analysis tools such as XDebug or Blackfire.
