A WordPress migration that makes your site slower means something went wrong in the setup. Glitch Servers NVMe UK hosting, configured correctly, makes WordPress significantly faster - not slower.
You're Not Alone
WordPress running slower after a hosting migration is a surprisingly common problem - and a fixable one. When a site moves to a new server but critical performance configurations aren't carried across or set up correctly, the new host's technically superior hardware provides no benefit. OPcache might be disabled. Object caching might not be configured. The wrong PHP version might be selected. Caching plugins that worked on the old server might conflict with the new server's caching stack. Migrating a WordPress site isn't just moving files and databases - it requires ensuring the performance stack is correctly configured on the new infrastructure.
Why This Happens
Post-migration slowdowns typically have one of several causes: OPcache disabled or misconfigured (PHP re-compiles every script on every request instead of caching bytecode); wrong PHP version selected (PHP 7.4 instead of 8.2 - significantly slower for modern WordPress); caching plugin conflicts (WP Super Cache or W3 Total Cache generating cache for the wrong domain or interfering with server-level caching); database credentials pointing to the wrong server (WordPress making remote database connections with high latency); or CDN/proxy configurations that were lost during migration.
The Real Cost
This isn't just a technical inconvenience - it has measurable effects on your business.
Worse load times on what should be better hardware
SEO ranking drops as Core Web Vitals worsen post-migration
Confusing configuration differences between old and new hosts
A WordPress site that loads slower after migration creates immediate user experience problems and SEO signal degradation. Visitors notice slow sites. Bounce rates increase. Google measures real-world Core Web Vitals from Chrome browser data and adjusts rankings accordingly. If a poorly configured migration makes your site 2 seconds slower, you may see ranking drops within weeks as the real-user data accumulates in Google's systems.
The Solution
When migrating to Glitch Servers, our team configures OPcache, selects the correct PHP version (PHP 8.2 by default for new WordPress installations), configures object caching via Redis where available, and verifies your caching plugin settings work with our LiteSpeed server and NVMe stack. For existing Glitch Servers customers whose WordPress is running slowly, our UK support team diagnoses the specific bottleneck - whether PHP configuration, database query performance, or caching - and resolves it directly.
What You Get
Infrastructure built to prevent these problems - not patch them after the fact.
OPcache is enabled and properly configured on all accounts. PHP scripts are compiled to bytecode once and cached in memory - eliminating repetitive compilation overhead on every WordPress request.
Choose PHP 7.4, 8.0, 8.1, 8.2, or 8.3 per domain via the Enhance Panel MultiPHP Manager. PHP 8.2 is 15–25% faster than PHP 7.4 for typical WordPress workloads. Our migration process sets the optimal version for your theme and plugins.
LiteSpeed web server with LSCache provides full-page caching at the server level - faster than plugin-based caching. The LiteSpeed Cache WordPress plugin is available via the one-click installer and integrates directly with server-level caching.
MySQL on NVMe Gen4 SSD storage returns query results in microseconds. The hundreds of database queries a typical WordPress page triggers are handled in milliseconds - the stack your theme and plugins are designed to run on.
One-Click Installs
Post-migration WordPress performance is verified by our team before migration is considered complete. OPcache status, PHP version, and caching configuration are checked. The one-click installer provides WordPress health monitoring tools to identify slow queries and plugin conflicts after launch.
All Glitch Servers Enhance Panel plans include one-click installation for WordPress, WooCommerce, and Joomla - free with every hosting plan.
