Each hosting plan has resource limits. Knowing them is important to pick the right plan and avoid hitting the ceiling.
Main limits:
- CPU (processor load) — measured in %. If the site constantly exceeds the limit — other sites on the server suffer, we are forced to temporarily suspend the account.
- RAM (memory) — how much a process can consume. Exceeding → process is killed, page fails.
- Disk — total volume for files, DB, mail, backups.
- Inodes — number of files and folders. Each email, each plugin, each cache file = 1 inode. Limit is usually 100k–500k.
- Entry Processes / IO — concurrent requests and disk speed.
How to check current usage:
cPanel → right sidebar → “Statistics” block shows current values and limits.
What to do when exceeded:
- Delete old backups and unused files.
- Install a caching plugin (LiteSpeed Cache, WP Rocket).
- Upgrade to a higher plan — upgrade in the client area.
