Common Hosting Problem

WordPress Slow After Migration

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 Slow After Migration

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

The Root Cause

What's really going on

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.

Damaged Reputation

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

How Glitch Servers Fixes This

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

Why Glitch Servers Is Different

Infrastructure built to prevent these problems - not patch them after the fact.

PHP OPcache Enabled by Default

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.

🛡️

MultiPHP - Correct Version Selection

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 + LSCache

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.

💬

NVMe Database Performance

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.

FAQ

Frequently Asked Questions

Most commonly: OPcache disabled, wrong PHP version, caching plugin misconfigured for the new server environment, or object cache not configured. Run a GTmetrix or PageSpeed test and compare TTFB with your old host to identify where the slowdown occurs.
Go to Enhance Panel → MultiPHP INI Editor → PHP Information for your domain. Search for "opcache.enable" - it should show "1" (enabled). If it shows "0" or is absent, contact support and we'll enable it immediately.
PHP 8.2 for most WordPress sites using mainstream plugins. PHP 8.3 if all your plugins declare compatibility. Avoid PHP 7.4 - it's end-of-life and significantly slower. Use MultiPHP Manager in the Enhance Panel to switch versions instantly.
Most do, but some configuration changes are needed. W3 Total Cache and WP Super Cache need their cache directories cleared after migration. We recommend switching to LiteSpeed Cache (free, integrates with our server-level caching) for best performance.
Yes - open a support ticket with your domain name. Our UK engineers access server-side PHP slow log, MySQL query log, and error log to identify the specific bottleneck. Most post-migration performance issues are diagnosed and fixed in a single support exchange.
