11 Common Causes For Slow-Loading Magento 2 Admin Panel

1. Cache Management

Cache plays an essential role in web applications. It prevents the server from processing the same request repeatedly. Using it effectively can save significant memory and execution time. However, if not managed properly, cache containers can become overloaded. Magento employs unique caching techniques. They utilize both disk and database to maintain smooth operation. It’s essential to clean your cache folder to avoid slow performance issues regularly.

$ [magento/var] > rm -rf cache/*

Cache allows the system to quickly retrieve previously accessed items. Neglecting regular cache cleaning can lead to a sluggish website.

There are various types of cache in Magento and their statuses. You can manually flush the Magento cache. Or, consider using a cache plugin for better management. To manage your cache, navigate to:

Admin Panel > System > Tools > Cache Management

Using Redis as your caching solution can significantly improve performance. Redis is an open-source in-memory data structure store. It offers a fast and efficient caching alternative. This is because all data is stored in memory rather than on disk.

The session folder also needs regular clearing to prevent it from growing excessively.

$ [magento/var] > rm -rf session/*

Sometimes, sessions are stored in the database. Hence, it's important to truncate the core_session table as well. Cache tables in the database can also pose issues. It's advisable to keep the core_cache_% tables empty. They can grow quickly, leading to database bloat and reduced performance.

2. Clean Up Unused Modules and Extensions

Many pre-installed modules/extensions are there that aren’t always necessary. It is advisable to delete unused extensions rather than just disabling them. Disabling a plugin leaves it in the database. It increases database size and slows down the reading times of the database.

Multiple modules with various functions enabled on a Magento website can significantly degrade performance. Plugins that perform redundant operations create hidden server loads.

Consider moving your administrator section to a separate server if possible. Then, profile all third-party modules on your store. Or remove or delete those you don't need.

Some custom extensions may overload the server due to unoptimized code. It can affect valuable performance indicators like Magento's time to first byte. Use a dedicated debug tool to examine each module thoroughly. If you're unsure, consider seeking professional Magento performance optimization services.

3. Delete Outdated, Unused, or Hidden Products and Categories

Each product consumes resources that can degrade administrator performance. Magento can handle an unlimited number of stock-keeping units (SKUs). However, keeping outdated products and categories on your site is not advisable. These items may not appear on the Magento storefront. However, Magento still processes them, which can slow down your admin area. This performance impact is more pronounced on weaker server configurations. Even powerful servers can benefit from periodic cleanup. If your store has thousands of unused products, it’s best to remove them. This will make your database faster in reading and searching operations.

Hundreds of product attributes and attribute sets can also slow down the Magento backend. It can create conflicting data. To delete an attribute:

1. Navigate to Stores > Attributes > Product.
2. Find the attribute you want to delete and open it in edit mode.
3. Click the "Delete Attribute" button and confirm the operation.

Magento 2 store does not support mass deletion of product attributes out of the box. Hence, each one must be removed individually. Deleting these products frees up space. It can result in a more efficient and less cluttered database.

Regularly cleaning up your store every few months will help maintain optimal speed. Caching and displaying only a limited set of products can speed up the front-end. However, the performance will still suffer if the database is overloaded.

4. Reindexing

By default, reindexe all products and categories in your store. It does this whenever a product or category is updated. This process ensures that the index reflects these changes. However, it can make both the store & Magento Admin section unresponsive during re-indexing.

It's advisable to remove automated reindexing after each product or catalog change. Instead, you can schedule reindexing to occur during off-peak hours.

To do this, navigate to System > Index Management. Depending on your Magento 2 version, the options may be labeled as "Real-time" or "On Save". It can trigger re-indexing every time a product is saved, causing slowdowns. Switching to "Update By Schedule" is more performance-friendly. It allows you to control when re-indexing occurs.

Once you've switched to scheduled re-indexing, you can manage the index via cron jobs or the command line interface (CLI). Schedule the re-indexing job during a time when your store traffic is low, such as "late at night". For large stores with many products (e.g., 100,000+ SKUs), re-indexing can take several hours. Hence, timing is important.

If you've never used cron before, you can install it with the following command:

php bin/magento cron:install --force

For most stores, cron is already installed. You'll need to add the following job to reindex all items daily at 3 AM:

0 3 * * * /usr/bin/php /path/to/your/site/root/bin/magento index:reindex <index_type>

Note: Remember, this schedule is based on your database's time zone. So, ensure it aligns with your desired timing. This approach prevents re-indexing from affecting your store during peak hours.

Reindexing is essential for maintaining product alignment. However, it can cause delays when saving products, especially for stores with many items. Instead of disabling re-indexing, which is not recommended, schedule it via shell commands to run during off-peak times. Magento provides enhanced CLI tools with the following command:

php bin/magento indexer:reindex

5. Optimize the Database

Optimizing MySQL is essential for enhancing database performance in Magento online store. A valuable tool for Database tuning is MySQLTuner a free. It is an open-source inspection tool. It helps identify major issues in your database configuration.

The below Perl script analyzes your database for potential problems. It provides recommendations to improve the speed of your store's performance. Its optimization advice is beneficial for both frontend and backend operations. It can also identify security vulnerabilities. To begin, download the script and make it executable:

wget //mysqltuner.com/mysqltuner.pl chmod +x mysqltuner.pl

Running the following command requires you to have your MySQL root password:

./mysqltuner.pl

The output is divided into two main sections.

1. Statistics: It highlights issues with your database. Examples include aborted connections, temporary tables, and outdated versions. Pay attention to any [!!] exclamation marks. They indicate problems that need fixing.
2. Recommendations: Offer guidance on what to prioritize for optimization.

The most important part of the report is the Common Vulnerabilities and Exposures (CVE) Security Recommendations. These may not directly affect performance. However, they are important for identifying potential database vulnerabilities.

In Magento 2.4 and later versions, MySQL was deprecated for catalog search. It can be replaced by Elasticsearch. It can significantly improve search speed and accuracy. To enable Elasticsearch:

1. Navigate to Stores > Settings > Configuration > Catalog > Catalog Search.
2. Configure the search engine to use your Elasticsearch endpoint.
3. Click "Test Connection".

6. Raise the Memory Limit

A lack of free memory on the server is a common issue with Magento installations. However, this problem results in a blank page or server error rather than slowdowns. Check how much memory your server allocates in the php.ini or .htaccess file. Allocate less memory than specified in Magento's system requirements. It will cause scripts to crash. It prevents the Magento site from opening.

To fix this, increase the memory limits. Save the changes and test your Magento backend performance. Increasing memory limits might require editing php.ini. You can also alter the HTTP access file. For expert assistance with managing server memory limits, reach out to your Magento consultants.

7. Choose Lightweight Themes

The theme used in your Magento store significantly affects load speed. Heavier themes can slow down your website and reduce overall performance. To address this, switch to a lightweight theme with only the essential code. Or, optimize your current theme to make it lighter. In some cases, developers use custom themes specifically designed for speed and performance.

For example, the Magento Responsive Administrator Template allows for various visual changes. It also allows for design customizations in the administrator interface. However, this doesn’t automatically enhance performance. Additional customization and optimizations are needed to achieve that.

Note: Modify the administrator dashboard theme and remove components like Knockout.js. It may cause certain modules to stop functioning. Developers must proceed cautiously and implement workaround solutions to avoid disruptions.

8. Upgrade to the Latest Magento 2 Version & PHP Version

Upgrading Magento to the latest version can resolve Magento 2 backend slow issues. Each new Magento release usually includes additional tweaks. It also involves features that help manage the back-end more efficiently. Resolve ongoing issues and bugs. Every release introduces new and improved capabilities.

For example, the latest Magento 2.4.6 version offers several GraphQL performance enhancements. It includes:

• Faster response times for product queries in categories with enabled permissions
• Improved GraphQL resolver operations
• Quicker processing of product permissions

Staying updated with new Magento releases speeds up bulk cart operations. Upgrading to the latest supported version of PHP, with OPcache enabled. It makes it easier to add large quantities of products at once.

9. Enable CDN for JavaScript File Merging

Combine all JS files into a single file. Reduce the number of HTTP requests your store makes to the server. However, to do this, you may need to edit certain parts of your code. To enable JS file merging, navigate to:

1. Stores > Configuration > Advanced > Developer > JavaScript Settings > Merge JavaScript Files > Yes.

This setting applies to the entire store, including the frontend. It can also improve speed and enhance your Magento Core Web Vitals.

To apply this change only to the Magento2 Admin Panel, you can:

2. Enable merging globally.
3. Disable it at the store level.

Note: You can't make this adjustment in the slow admin section when in production mode. You'll need to do this directly in the database or via commands.

Consider configuring a Content Delivery Network (CDN) to store media. You can also keep static assets on edge servers closer to your customers. It can result in faster response times. To configure a CDN,

1. Navigate to Stores > Settings > Configuration.
2. Under General, select Web and expand the Base URL sections.
3. Update the Base URL for Static View Files and the Base URL for User Media Files.

Note: Do this with the URL of your CDN endpoint where the static view and JS files are stored.

10. Activate Production Mode

For a live Magento ecommerce store, it’s essential to operate in Production mode. Running the platform in Developer or Default mode can slow down performance. In these modes, Magento uses a PHP script to process all static files. Production mode, however, bypasses this script for a faster, though less flexible, approach.

Connect to your Magento 2 installation via secure shell protocol (SSH). Execute the following command:

php bin/magento deploy:mode:set production

11. Optimize Images & Create High-Quality Content

Many websites still use outdated and unoptimized images. It can slow down page load times. For MGT Commerce's clients, you can enable Varnish, a web application accelerator. It can significantly speed up the loading of static images. MGTt has a page load time of under 0.3 seconds.

Search engines favor fresh, high-quality content. It engages and informs your target audience. Regularly updating your blog with new content puts you on the right track. It improves your visibility in Search Engine Results Pages (SERPs). Effective Magento SEO is key to building a stronger marketing strategy. It can elevate your business.

Best Practices For Optimizing Magento Admin Panel Performance
