Shared hosting gives every account a fair slice of the server, enforced by a few limits:
- CPU - how much processor time your scripts can use. Heavy or unoptimized code can max this out.
- Entry Processes (EP) - the number of scripts running at the same instant (not total visitors). Long-running PHP requests count here.
- IO - how fast your account can read/write to disk, measured in KB/s.
- IOPS - the number of read/write operations per second.
When you exceed a limit, requests are briefly queued or you may see a 508 Resource Limit Reached error. Caching, image optimization and removing heavy plugins all reduce this load. You can view current usage in cPanel under Resource Usage. If you regularly hit your limits, you may need a larger plan or a VPS - open a ticket and we'll advise.
