Community Q&A

Does server CPU core count matter for WordPress speed?

Single-core performance is more critical for WordPress than high core counts, as it directly impacts PHP execution speed and admin responsiveness.

Should I optimize plugins or server hardware first?

Always audit and fix slow plugins or inefficient database queries first, as hardware upgrades rarely compensate for poorly optimized code.

How can I improve PHP performance on a budget?

Tuning your PHP-FPM pools, specifically the pm.max_children calculation, is the most effective way to handle high concurrency on limited resources.
