Optimizing Magento for performance

Magento is a resource‑intensive application, and without proper tuning it can run slowly on standard shared hosting. On ruachost.com, you can apply several optimizations to improve speed, responsiveness, and scalability.

Server Requirements

Minimum 16GB RAM recommended; 32GB RAM for large stores.
Use a Managed VPS for best results.
Shared hosting accounts are not sufficient for full Magento deployments.

Key Optimization Steps

1. Configure Cron Jobs

By default, Magento cron runs every 15 minutes.
This can cause unnecessary load.
Adjust cron frequency to reduce performance impact.

2. Optimize Logging

Magento’s default log settings can cause databases to grow very large.
Clean log tables regularly to reduce database size.

3. Enable Caching

Magento includes several built‑in caches.
Go to System → Cache Management and ensure all caches are Enabled.

4. Disable Local Modules (Magento 1.9 only)

If app/code/local is empty, disable local modules in app/etc/local.xml:
```
<disable_local_modules>true</disable_local_modules>
```

5. Apache Optimizations

Enable mod_deflate for compression.
Enable mod_expires for browser caching.
Merge and minify JavaScript and CSS files.

6. Use Flat Catalogs

Flat catalogs merge product and category data into single tables.
This reduces complex SQL queries and improves database performance.

7. Eliminate 404 Errors

Ensure your store does not contain links to nonexistent resources.
Each 404 triggers Magento, increasing CPU load.

8. Disable Unused Module Output

Go to Stores → Configuration → Advanced → Advanced.
Disable output for unused modules to reduce overhead.

9. Developer Debugging (Magento 1.9 only)

Ensure debugging options are disabled in production.
Profiler and logging should be set to No.

Important Notes

Always back up your site before applying performance changes.
Test optimizations in a staging environment before production.
Ruachost Managed VPS accounts support advanced caching (Redis, Memcached, LiteMage).
