When you are hitting limits.
WHAT LIMITS EXIST
CPU
Memory Entry processes, meaning simultaneous requests Input and output operations
THE SYMPTOM
Intermittent slowness, or errors under load, rather than consistent slowness.
HOW TO CHECK
cPanel shows resource usage against your limits.
Look for whether you are hitting them and when.
WHAT USUALLY CAUSES IT
No caching, so every visitor causes full processing Bot traffic, which on many small sites exceeds human traffic A plugin doing heavy work on every request Backups running during busy periods A badly configured cron job
THE BOT POINT
Frequently the largest single cause and entirely invisible without looking.
WHAT TO DO FIRST
Enable caching. That resolves most resource problems on small sites.
WHEN AN UPGRADE IS WARRANTED
When legitimate traffic genuinely exceeds what the plan provides.
Not before you have tried caching.
WHAT TO ASK US
Open a ticket with what you have found. We will tell you honestly which applies.
