They told you: "More RAM means your site handles more traffic."

They told you: "More RAM means your site handles more traffic."

The spec sheet shouts RAM because RAM sounds like horsepower. Follow what actually serves your visitors.

The real comparison:
— RAM: matters, but it's not the gate. A 4GB box with 2 PHP workers still queues visitor #3.
— PHP worker count: THIS is your concurrency ceiling. 2 workers = 2 simultaneous uncached requests, then everyone waits.

Managed hosts cap workers low and never put the number on the pricing page — but they'll print the RAM in 40pt font.

The limit they advertise is rarely the limit that throttles you.

Reality: ask for the PHP worker count — that, not RAM, decides who waits in line.
