Community Q&A

Does CPU core count matter for WordPress speed?

Single-core performance is more critical than total core count for WordPress admin responsiveness and overall site speed.

How can I improve WordPress concurrency?

Tuning PHP-FPM settings, specifically pm.max_children, is essential for handling high traffic on a budget.

Is server-side caching better than plugins?

Yes, using server-level solutions like Redis or optimized stacks often prevents the noisy neighbor problem found in shared hosting.
