Understanding your resource limits (CPU, RAM, entry processes and I/O)

Your hosting account runs on a shared server with other customers. To keep every website fast and stable, each account has its own set of resource limits. If one website gets very busy or has a problem, it slows down within its own limits instead of affecting everyone else.

What each limit means

Limit What it measures What happens when you reach it
CPU Processing power your website uses Your website slows down
Physical memory (RAM) Memory used by your website's scripts Some requests fail, often with a 500 or 503 error
Entry processes How many requests your website handles at the same moment New visitors see a "508 Resource Limit Reached" error
Processes The total number of processes running for your account New requests fail with a 500 or 503 error
I/O and IOPS How fast your account can read from and write to disk Your website slows down
Inodes (files) How many files and folders your account has Nothing is blocked. This is a soft limit. We contact you and ask you to reduce the number of files.

Your limits

These limits apply to every Web Hosting plan. Disk space, bandwidth, websites and email accounts vary by plan and are shown on our Web Hosting page.

Resource Limit
CPU The equivalent of one core, sustained. Brief spikes are fine.
Memory (RAM) 1 GB
Concurrent processes 25
Inodes (files and folders) 250,000
Database size 2 GB per database
Outgoing email 300 messages per hour
Cron jobs No more than once every 5 minutes

Checking your usage

  1. Log in to DirectAdmin.
  2. Go to Extra Features and click Resource Usage.

You'll see your usage over time and any occasions when you reached a limit. Occasionally reaching a limit during a busy moment is normal. Reaching limits often means your website needs attention.

If your website regularly reaches its limits

Our first step is always to contact you. A website that has outgrown its plan usually just needs a bigger one. We only suspend an account in two cases: when it's affecting other customers and we can't reach you, and when the over-use is deliberate.

Reducing your usage

  • Turn on caching. For WordPress, see Speeding up WordPress with LiteSpeed Cache. Cached pages use a fraction of the resources.
  • Remove unused plugins and themes, especially heavy ones such as page builders, security scanners and statistics plugins you don't need.
  • Block unwanted bots. Aggressive crawlers can use a lot of resources. Ask us if you notice unusual traffic.
  • Check for malware. Unexpected spikes can be a sign of a compromised website. See Scanning for and cleaning malware with Imunify360.
  • Upgrade your plan if your website has outgrown it. See Upgrading or downgrading your hosting plan.
