Joomla vs WordPress Hosting: The Differences That Actually Matter

Joomla and WordPress both run on PHP and a MySQL-compatible database. On paper, their hosting requirements look almost identical. In practice, the two CMSes behave differently under load, use the database in different patterns, and benefit from different server-level optimizations.

This isn't a "which CMS is better" debate. It's a practical guide for anyone deciding how to host one (or both) of these platforms—and what to ask a hosting provider before signing up.

The basics: where Joomla and WordPress overlap

Both CMSes share a common foundation:

• Runtime: PHP (8.1+ recommended for both)
• Database: MySQL 8.0+ or MariaDB 10.4+
• Web server: Apache or Nginx
• HTTPS: effectively required for both

A hosting account that can run one can technically run the other. The differences show up in how each CMS uses those resources—and how a host can optimize for each.

Architecture differences that affect hosting

WordPress: lightweight core, heavy plugin dependency

WordPress core is compact. A fresh WordPress installation has minimal built-in functionality—it's a blogging engine with basic page management. Everything else comes from plugins and themes:

• eCommerce: WooCommerce
• Forms: Gravity Forms, WPForms, etc.
• Page building: Elementor, Divi, Gutenberg blocks
• SEO: Yoast, Rank Math
• Security: Wordfence, Sucuri, etc.

This means a WordPress site's server footprint depends enormously on which plugins are installed. Two WordPress sites on identical hosting can perform completely differently based on plugin choices.

Joomla: more built-in, fewer extensions needed

Joomla's core includes features that WordPress requires plugins for:

• Multilingual content management — built into Joomla core (WordPress needs WPML or Polylang)
• User access control (ACL) — granular permission system in core (WordPress ACL is basic without plugins)
• Content categories — nested category system built in
• Contact management — core component
• Custom fields — native support without extensions
• Content versioning — built-in revision history

The result: a typical Joomla site runs fewer third-party extensions than a comparable WordPress site. But Joomla's core is larger and its built-in features create more complex database queries.

Database usage: the biggest hosting difference

This is where the two CMSes diverge most, and where hosting configuration has the biggest impact.

WordPress database patterns

WordPress uses a relatively simple database schema. The core has 12 tables. The wp_options table is heavily used for settings, transients, and plugin data—and it's often the bottleneck on slow WordPress sites.

Key patterns:

• High read volume on wp_options and wp_postmeta (especially with WooCommerce and page builders)
• Autoloaded options can grow large and slow down every page load
• Transients (cached data stored in the database) accumulate and add overhead
• Many plugins create their own tables, leading to schema bloat over time

The hosting optimization: persistent object caching (Redis or Memcached) dramatically helps WordPress by caching repeated option and transient lookups in memory instead of querying the database every time.

Joomla database patterns

Joomla uses a more normalized database schema with more tables (30+ in core alone). The ACL system, nested categories, and multilingual content create complex JOIN queries.

Key patterns:

• Complex JOINs for content retrieval (articles + categories + ACL checks + language filters)
• ACL lookups on most requests — even viewing a page triggers permission checks
• Content versioning adds rows per save, which grows the database steadily
• Nested set model for categories — powerful but query-intensive for deep hierarchies

The hosting optimization: InnoDB buffer pool size matters more for Joomla because its queries touch more tables and indexes. A well-configured buffer pool keeps these indexes in memory. Redis/Memcached helps too, but Joomla's query patterns mean database engine tuning has a bigger relative impact than with WordPress.

PHP resource usage compared

Memory consumption

• WordPress: a basic site uses 40–80 MB per request. With WooCommerce and a page builder, this can reach 128–256 MB.
• Joomla: a basic site uses 50–90 MB per request. With complex ACL and large component extensions, this can reach 128–512 MB.

Both need at least 256 MB memory_limit in production. Joomla's ACL system can push memory higher during admin operations (like editing permission configurations for many user groups).

OPcache requirements

Both CMSes benefit enormously from OPcache. The difference is in scale:

• WordPress core: ~1,500 PHP files
• Joomla core: ~4,000+ PHP files

Joomla needs more OPcache memory to hold its compiled bytecode. If your host allocates 128 MB for OPcache (a common default), WordPress fits comfortably but Joomla with extensions may exceed it—forcing PHP to evict cached files and recompile them, which defeats the purpose.

Recommendation: 256 MB OPcache memory for Joomla, 128–192 MB for WordPress (more if using many plugins).

PHP workers

Both CMSes need adequate PHP workers for concurrent visitors. The difference is in cached vs uncached request ratios:

• WordPress with a good caching plugin (WP Super Cache, W3 Total Cache, LiteSpeed Cache) serves most public pages as static HTML, bypassing PHP entirely. This means fewer requests hit PHP workers.
• Joomla's built-in caching is less aggressive by default. Page caching exists, but Joomla's ACL system means many requests still hit PHP to check permissions—even for public content.

Result: a Joomla site at the same traffic level typically needs more PHP workers than a similarly configured WordPress site, because more requests pass through PHP.

Caching strategies: different approaches

WordPress caching

WordPress has a mature caching ecosystem:

• Full-page caching — plugins generate static HTML for public pages. Extremely effective for blogs and marketing sites.
• Object caching — Redis/Memcached for wp_options, transients, and session data. Critical for WooCommerce and membership sites.
• Browser caching — standard HTTP headers
• CDN integration — CloudFlare, StackPath, etc.

The WordPress caching approach is well-documented, widely supported by hosts, and has mature tooling.

Joomla caching

Joomla has built-in caching, but the approach is different:

• Page caching — Joomla can cache full pages, but ACL-aware content means cache invalidation is more complex. If different user groups see different content, page caching has more exclusions.
• View caching — caches individual module and component output rather than full pages. More granular but less impactful than full-page caching.
• Conservative caching — available in Global Configuration. Safer for dynamic sites but provides smaller performance gains.
• External caching — Redis and Memcached supported as cache storage backends.

The hosting implication: a WordPress host that relies heavily on "our caching makes WordPress fast" may not have the database tuning and PHP configuration that Joomla needs—because Joomla can't cache its way past every performance issue the way WordPress often can.

Security considerations

WordPress security profile

WordPress is the most attacked CMS on the internet—not because it's insecure, but because it powers 40%+ of websites. The massive plugin ecosystem is the primary attack surface:

• Vulnerable plugins are the #1 WordPress security issue
• The REST API and XML-RPC are common attack vectors
• Brute-force attacks on /wp-login.php are constant

WordPress hosting should include: WAF rules for WordPress-specific attacks, brute-force protection on login, and ideally automated malware scanning.

Joomla security profile

Joomla has a smaller market share, which means fewer automated attacks—but also fewer security researchers auditing extension code:

• Extension vulnerabilities are the primary concern (same as WordPress, but with less community scrutiny)
• The /administrator path is predictable and targeted
• Joomla's ACL complexity means permission misconfigurations can expose content unintentionally

Joomla hosting should include: WAF protection, brute-force protection on the admin login, file integrity monitoring, and malware scanning. The admin path protection is especially important—unlike WordPress where you can easily change the login URL with a plugin, Joomla's admin path is harder to relocate.

When a host says "we support both"

Most shared hosts technically support both Joomla and WordPress. But "supports" and "optimized for" are different things.

Questions to ask if you're hosting Joomla:

• Is OPcache configured with enough memory for Joomla's file structure? (256 MB recommended, not the default 128 MB)
• What's the InnoDB buffer pool allocation? (Joomla's complex queries need this to be adequately sized)
• Does your support team have experience troubleshooting Joomla? (WordPress-only expertise doesn't help when Joomla's ACL system is misconfigured)
• Can you handle Joomla-specific migrations? (Joomla uses Akeeba Backup, not WordPress export/import)
• Do you monitor for Joomla-specific security vulnerabilities? (The attack patterns differ from WordPress)

If the host can only answer WordPress questions confidently, they're a WordPress host—even if their website says "we host all CMSes."

Hosting both on the same account

It's common (especially for developers and agencies) to run both Joomla and WordPress sites on a single shared hosting account using addon domains.

This works, but keep in mind:

• PHP version conflicts — Joomla 5.x and modern WordPress both need PHP 8.1+, so this is less of an issue now than it used to be. But if you're running an older Joomla 3.x site alongside WordPress 6.x, you may need per-directory PHP version control.
• Resource sharing — both sites share the same PHP workers, memory, and CPU. A traffic spike on one affects the other.
• Database performance — both sites share the same MySQL instance. Joomla's complex queries during ACL operations could slow WordPress database access during peak times.
• Backup management — account-level backups capture everything, but restoring one site means restoring the whole account. Consider per-site backup tools (Akeeba for Joomla, UpdraftPlus for WordPress) for independent restore capability.

If both sites are business-critical, consider separate hosting accounts (or at minimum a semi-dedicated plan) to avoid resource contention.

FAQs

Can I run Joomla and WordPress on the same hosting account?

Yes. Both run on PHP and MySQL, so any hosting account that supports one supports the other. Use addon domains in cPanel to host multiple sites. Just be aware that both sites share resources—if one gets heavy traffic, the other can be affected.

Is WordPress faster than Joomla?

Not inherently. WordPress with good full-page caching can serve public pages extremely fast because PHP is bypassed entirely. Joomla's ACL system means more requests pass through PHP. But the raw PHP execution speed is similar—the difference is in caching strategy and database query complexity, both of which depend on hosting configuration.

Which CMS is easier to host?

WordPress is easier to host in the sense that its caching ecosystem is more mature and its database patterns are simpler. Joomla requires more attention to PHP configuration, OPcache sizing, and database tuning. A host that's properly configured for Joomla will also run WordPress well—but the reverse isn't always true.

Should I switch from Joomla to WordPress?

That depends on your needs, not your hosting. Joomla's built-in multilingual support, ACL system, and content structure tools are genuinely better than WordPress's equivalents. If you're using those features, switching to WordPress means adding multiple plugins to replace what Joomla gives you natively. If you're running a simple blog or business site, WordPress's larger ecosystem of themes and plugins may be an advantage. See our Joomla migration guide if you're considering a move.
