Quick answer: In cPanel, look for Metrics → Resource Usage (if your host provides it). Review CPU, physical memory, entry processes and I/O over several days, especially when the site feels slow. A single spike does not automatically mean you need a bigger hosting package.

Why check resource usage?
It is easy to assume that every slow website needs more expensive hosting. Sometimes it does; often the cause is a poorly configured plugin, an uncached page, a large image or background tasks. Looking at your account’s resource history helps you separate occasional spikes from persistent limits.
The precise cPanel screens depend on your provider and the limits applied to your account. If you do not see Resource Usage, ask your host what monitoring they provide.
How to find the information in cPanel
- Sign in to your cPanel account.
- Look under Metrics for Resource Usage, if available.
- Open the current usage view, then check the historical graphs or detail pages.
- Compare busy times with periods when your website felt slow or returned errors.
- Note any warnings about account limits, but do not assume every alert requires an upgrade.
Some hosting environments use CloudLinux resource controls; others may show different statistics or none at all. Your provider can clarify what each metric means for your package.
What the common metrics mean
CPU usage
CPU is the processing time your site uses for PHP, database queries and other work. Repeatedly hitting a CPU allocation during normal traffic could point to a busy or inefficient site. A brief spike while updating WordPress or generating a backup may be expected.
Physical memory
This refers to memory used by processes running under your hosting account. A memory limit can matter when several PHP requests run at once or a plugin performs demanding work. It is different from the WordPress PHP memory limit configured within the application.
Entry processes and concurrent requests
Entry processes measure concurrent work entering the account in some shared hosting configurations. A sudden burst of uncached requests can reach the limit even with modest overall traffic. Bots, cron jobs and heavy admin tasks can also contribute.
Disk I/O and IOPS
These relate to how quickly the account can read and write data. Repeated limits can affect sites that generate many files, manipulate images or do heavy database work. A website’s performance depends on more than the type of storage advertised.
Five checks before paying for an upgrade
- Check whether limits are persistent. One unusual hour is not enough to judge typical requirements.
- Look at site speed and caching. Test a normal page and a logged-in page separately; their workloads can differ.
- Review recent changes. Did the problem begin after a new plugin, theme, import or scheduled task?
- Inspect errors. Ask your host to help correlate resource limits with server logs, PHP errors and actual visitor impact.
- Compare plan allocations. An upgrade only helps if it addresses the constrained resource. More storage will not solve a CPU bottleneck.
When an upgrade can make sense
An upgrade is worth considering when normal visitor traffic repeatedly reaches the account’s limits, optimisation has already addressed obvious inefficiencies, and your provider confirms that the next package offers meaningful additional capacity. Growing online shops, larger membership sites and high-traffic WordPress sites may outgrow entry-level shared hosting.
If the bottleneck is a specific plugin or slow database query, moving plans might only disguise the problem temporarily. Ask for evidence of the constraint before committing to a higher recurring bill.
Frequently asked questions
Does a high CPU spike mean my site is broken?
No. Updates, traffic bursts and scheduled work can cause brief increases. Persistent saturation alongside slow pages or errors is more informative.
Is cPanel Resource Usage available on every account?
No. Availability depends on the host’s platform and enabled features. Contact your provider if you cannot find it.
Will a bigger hosting plan automatically improve Google rankings?
No. Better resources may improve performance when resource limits are genuinely the problem, but an upgrade is not a direct SEO ranking guarantee.
Can I investigate this without changing my site?
Yes. Start by reviewing graphs and noting when issues occur. Avoid disabling essential security or backup tools just to make a graph look better.

Compare what your website needs with the resources supplied by your package. For general guidance, read our guide to hosting plan upgrades. If you are unsure what your account’s graphs mean, ask your provider to interpret them before spending money.
