Frequently Asked Questions

Core Technical Specifications

Q1 What is the optimal server software stack for high-performance WordPress on a UK VPS? +
A
The gold-standard high-performance WordPress stack combines NGINX (with FastCGI microcaching) or OpenLiteSpeed, PHP 8.3 with OPcache, MariaDB 10.11 with an optimized InnoDB buffer pool, and Redis Object Cache Pro for persistent database query caching.
Q2 How does Redis Object Cache accelerate dynamic WordPress page generation? +
A
Redis stores recurring database query results (such as site options, post metadata, user roles, and menu trees) directly in volatile RAM, eliminating hundreds of repetitive MySQL disk reads on every page view and slashing PHP execution time by up to 70%.
Q3 Why does NGINX FastCGI caching dramatically lower server TTFB compared to Apache? +
A
NGINX FastCGI caching stores rendered static HTML copies of dynamic pages in server memory and serves them directly to visitors without executing PHP or querying the database, dropping Time to First Byte (TTFB) from 600ms down to sub-50ms.
Q4 How should you calculate PHP-FPM pool settings (`pm.max_children`) for high traffic? +
A
Use the formula: `pm.max_children = (Available System RAM for PHP) / (Average PHP Process Size)`. For example, with 4000MB dedicated to PHP and an average worker footprint of 80MB, you set `pm.max_children = 50` to safely maximize concurrency without triggering out-of-memory crashes.

Deployment & Operational Inquiries

Q5 What is the minimum RAM required to run a fast WordPress site with heavy page builders? +
A
WordPress sites utilizing Elementor, Divi, or WooCommerce require a minimum of 2GB to 4GB RAM to comfortably accommodate background cron tasks, object caching, and PHP memory limits of at least 256MB to 512MB per process.
Q6 Does hosting WordPress on a London VPS improve Google Core Web Vitals (LCP) for UK visitors? +
A
Yes. Colocating your WordPress database and web server in a London tier-3 data centre minimizes round-trip network hops to UK visitors (sub-15ms), directly accelerating the Largest Contentful Paint (LCP) metric tracked by Google’s Chrome User Experience Report (CrUX).
Q7 How do you configure OPcache memory allocation in `php.ini` for optimal WordPress speed? +
A
Set `opcache.memory_consumption = 256`, `opcache.interned_strings_buffer = 64`, `opcache.max_accelerated_files = 30000`, and `opcache.validate_timestamps = 0` (in production) to keep pre-compiled PHP bytecode cached permanently in memory.
Q8 Can you automate WordPress database optimization and plugin updates via WP-CLI cron jobs? +
A
Yes. You can schedule crontab commands like `wp db optimize` and `wp core update` to execute silently at night, preventing unoptimized overhead tables and keeping core software secure without manual dashboard intervention.
