MySQL vs MariaDB: Which Database Powers a Faster Site

If you have ever opened your hosting settings and spotted the words "MySQL" or "MariaDB", you probably wondered whether the choice actually matters. Short answer: for most WordPress sites both will work fine, but there are real differences in speed, licensing and future direction that are worth understanding before you pick a plan or migrate a site.

Why there are two databases

MariaDB was created in 2009 after Oracle acquired MySQL. The same people who built MySQL created MariaDB as a fully open source alternative. For the first few years they were nearly identical — you could swap one for the other and your site would not notice. Today they have diverged: MariaDB has its own storage engines (Aria, ColumnStore), while MySQL 8 introduced its own advances such as better JSON handling and CTE queries.

Real-world speed

For a typical WordPress site with a few thousand visits per day, the speed difference is usually under 5–10%, which a visitor will never feel. MariaDB often performs better on queries with many concurrent connections (say a WooCommerce store at peak), while MySQL 8 can be faster on complex JOIN queries. What truly affects your site speed is not the database name but whether your tables are well indexed and whether you have caching. We covered this in detail in our guide to database indexes for a faster WordPress and in the article on cleaning and speeding up your database.

WordPress compatibility

WordPress officially supports both MySQL (5.7+) and MariaDB (10.4+). Popular plugins run on both. Problems appear only in rare cases: some older plugin expects specific MySQL syntax or a function that behaves differently in MariaDB. In practice this affects fewer than 1% of sites, and there is almost always a fix in the form of a plugin update.

What we use and why

On SEOhosting.rs servers we use MariaDB because it pairs beautifully with a LiteSpeed environment and NVMe disks, delivers stable performance under load and is fully open source. Combined with OPcache for PHP, the database rarely becomes the bottleneck. If you are coming from a host that uses MySQL, the migration is seamless — the data format is compatible and your site will not notice the difference.

When the difference truly matters

• Large stores: if you have 50,000+ products and many concurrent buyers, MariaDB advanced engines can deliver a measurable edge.
• Specific applications: custom apps using MySQL 8 JSON functions may require MySQL specifically.
• Analytics over huge tables: MariaDB ColumnStore was built for exactly these scenarios.

For 95% of users the choice between MySQL and MariaDB is not the factor deciding your site speed — how fast the server is and how well the site is optimised matters far more. Take a look at our hosting plans or learn more about SEO hosting that ships with NVMe disks, a free CDN and daily backups.

Conclusion

MySQL and MariaDB are relatives, not rivals. For WordPress both work great; MariaDB offers an open licence and excellent performance under load, while MySQL 8 shines in specific technical scenarios. Focus your energy on indexes, caching and hosting quality — that is where real speed is actually won.
