How To Reduce CPU Usage On GoDaddy (AKA Bandwidth Limits / Throttling Which Can Also Cause 503 Service Unavailable Errors)

If you’re getting CPU overages on GoDaddy, it means your website (and plugins) are consuming too many server resources.

To reduce high CPU usage on GoDaddy and stay within limits, login to GoDaddy and activate the CDN and PHP 7.3. Remove any high CPU plugins, database junk, and install Autoptimize. Lighten the load on your server using the Heartbeat Control plugin and blocking bad bots from Wordfence. It’s also likely you’re running too many resource intensive tasks for shared hosting. Shared hosting (especially GoDaddy) can’t handle big plugins like WooCommerce or Elementor.

GoDaddy obviously wants you to upgrade, but hopefully after reading this guide, you won’t have to. Until then, you may be getting 503 errors which means you exceeded your CPU limits.

1. Check Bandwidth Usage

Check how much bandwidth you’re actually using (in GoDaddy’s cPanel go to Web Hosting > Manage > Bandwidth). Next, review GoDaddy’s bandwidth limits and compare them to yours.

Quick Tips For Reducing Bandwidth:

  • Check CPU usage in GoDaddy cPanel
  • Upgrade to PHP 7.3 in your GoDaddy cPanel
  • Delete unnecessary plugins you can live without
  • Install Autoptimize plugin to optimize HTML, CSS, JavaScript
  • Resize large images to be smaller (serve scaled images in GTmetrix)
  • Losslessly compress images using the ShortPixel image optimization plugin
  • Install Heartbeat Control, WP-Optimize, and Blackhole For Bad Bots plugins
  • Use other tools in GoDaddy cPanel (eg. AWstats) to locate the source of high CPU

 

If you have high quality images on your site, people may by copying and pasting them onto their own website (or even Facebook and other social networks). This means you’re still hosting them, which sucks up your bandwidth. Here’s how to prevent this using hotlink protection which can be activated in GoDaddy’s cPanel or Cloudflare’s scrape shield settings.

In GoDaddy:

  • Login to your GoDaddy cPanel
  • In the Security section, click Hot Link Protection and enable it

In Cloudflare:

  • Sign into your Cloudflare account
  • Go to your Scrape Shield settings
  • Enable hotlink protection

3. Upgrade To PHP 7.3

Upgrading PHP versions makes your site load faster (and improves security). Anytime GoDaddy releases a new PHP version, you should try to upgrade. Unfortunately, many WordPress users run outdated PHP versions since GoDaddy does NOT automatically upgrade you, since it can break your site if you’re running incompatible plugins. Here’s how to upgrade.

How To Upgrade To PHP 7.3

  • Login to your GoDaddy cPanel
  • In the Software section, click Select PHP Version
  • Change to PHP 7.3
  • Check your website for errors
  • If you see errors, run PHP Compatibility Checker to ensure your plugins are compatible
  • If you still see errors, revert to an earlier PHP version

Upgrade PHP Version GoDaddy

Unfortunately, if you don’t have a GoDaddy plan with cPanel, it is not available to you. Many GoDaddy customers aren’t happy about this, and it’s another drawback to using their hosting.

GoDaddy says:

“PHP 7 is available for cPanel customers on either Shared or Business Hosting.”

 

4. Heartbeat Control

The WordPress Heartbeat API shows real-time plugin notifications, and when other users are editing a post. This consumes server resources and should be limited, or disabled. Install the Heartbeat Control plugin and limit it to 60 seconds, or ideally, disable heartbeat completely.

5. Clean Database With WP-Optimize

Your database can get bloated by accumulating junk files like post revisions, spam comments, transients, pingbacks, trackbacks, and other junk which can be cleaned with WP-Optimize. It’s a good idea to clean your database once every 1-2 weeks, and take a backup before doing so.

6. Black Bad Bots

Spam bots are notorious for crawling websites and consuming server resources. If you don’t set rules for bots to follow (eg. using the Blackhole For Bad Bots plugin) they will continue to crawl your website, and you will be spending server resources (and money) on literally nothing.

Blackhole for Bad Bots

Check If Spam Bots Are Hitting Your Site

  • Install Wordfence
  • Go to your Live Traffic Report
  • Watch all bots hitting your site in real-time
  • If you don’t recognize a bot, Google it’s hostname (provided by Wordfence)
  • See if other people report the bot as spam (compute.amazonaws.com is a common one)
  • Block the spam bots using the Blackhole For Bad Bots plugin (you can also use Wordfence’s blocking tab or Cloudflare Firewall Rules to block spammy bots by using their hostnames… be sure to use asterisks which blocks all variations of the bot)

Block Spam Comments Too!
Spam comments also consume resources. I use Anti-Spam to block comment spam.

 

7. Eliminate High CPU Plugins

Some plugins are known for consuming lots of server resources and will cause CPU overages. Too many plugins (one just 1 single high CPU plugin) can absolutely destroy your load times and bandwidth usage. I created an extensive list of known high CPU plugins you should avoid.

You can also use GTmetrix’s Waterfall tab to find slow plugins:

Or use Query Monitor to see which plugins take longest to load:

8. Delete Unused Plugins + Themes

9. Autoptimize

GoDaddy has their own built-in caching system and blacklists all cache plugins. The problem is, cache plugins do a lot more than just caching (eg. minification and Google Font optimization). Autoptimize takes care of most of these miscellaneous optimizations, and can fix many items in GTmetrix/Pingdom. I have a full tutorial on configuring Autoptimize, but it’s pretty simple:

Autoptimize-Main-Settings

Autoptimize-Extra-Settings

 

10. Use A CDN

Cloudflare’s free CDN will help offload resources to their 200+ data centers around the world, lightening the load on your own server. It will also reduce the geographic distance between your server and visitor, making your website load much faster for people who were far away from your 1 origin server. A CDN is also recommended in the WordPress optimization guide.

Step 1: Sign up for a free Cloudflare plan.

Step 2: Add your website and run the scan. You will come to a page with 2 nameservers.

Cloudflare-Nameserver-Dashboard.

Step 3: Change nameservers in your GoDaddy account to Cloudflare’s.

11. Optimize Images

There are 3 primary ways to optimize images in GTmetrix, however you should really check out my full WordPress image optimization tutorial which includes 20 ways to optimize images.

12. Clear Out Disk Space

You should try to leave about 20% of your GoDaddy disk space empty. Make sure you’re optimizing images, deleting unused images, plugins, themes, and other files on your website.

 

13. GoDaddy Speed Limitations

No serious website should use GoDaddy for hosting. It is mainly for beginners who are just starting their website and are concerned about 1 thing – price. But with this, comes with speed limitations which are reflected in your server response times, GTmetrix, and Pingdom reports.

  • GoDaddy is slow at releasing PHP versions (and are only available on cPanel plans)
  • GoDaddy blacklists cache plugins (which can improve speed more than Autoptimize)
  • GoDaddy uses outdated server hardware, resulting in slower server response times
  • GoDaddy puts too many people on the same server, resulting in slow response times
  • This is why their hosting is so cheap, because 100s of people share the same server

14. Get Better Hosting (GoDaddy Sucks)

Most people in the WordPress Hosting Facebook Group swear by Cloudways.

Specifically their DigitalOcean or Vultr High Frequency plan. Yes, it’s a little more expensive at $10-$13/month, but we’re talking about speed – not being cheap. This is the #1 factor in the WordPress optimization guide. Spend 2 minutes looking at this Facebook thread (and this one).

Backlinko reported SiteGround had some of the worst TTFBs. GoDaddy and EIG brands (Bluehost + HostGator) are cheap shared hosting and are obviously not good choices either.

Recent Facebook polls show a large shift in people moving away from lower quality hosts (including SiteGround) to Cloudways, LiteSpeed servers, Kinsta, GridPane, and A2 Hosting.

I personally use Cloudways DigitalOcean:

Cloudways Shoutout

Request a free migration from Cloudways (or another cloud host rated highly in polls) and enjoy the faster load times like many people already have. Cloudways has 3-day trials, a Migrator plugin, and promo code OMM25 gets you 25% off the first 2 months.

Cloudways Facebook Review

This is a simple Pingdom test to measure TTFB + load times of 16 WordPress hosts. I installed the same Astra Starter Site on 16 hosting accounts (using separate domains) while measuring Pingdom load times for 1 week at 30 minute check intervals, as well as TTFB in various tools. Some domains are still live (cwdoserver.com is hosted on a $10/month Cloudways DO plan and stgrndserver.com is on SiteGround GrowBig). I cancelled most accounts since it got expensive. Even when browsing through these 2 sites or running your own tests, you’ll see the difference.

WordPress-Hosting-2020-Pingdom-Test

Hosts To Avoid

  • GoDaddy – top malware hosting network worldwide, rated poorly in FB groups.
  • Bluehost – slow servers, owned by EIG, slow support, rated poorly in FB Groups.
  • HostGator – also owned by EIG with slow servers, bad support, CPU limit issues.
  • Hostinger – they write fake reviews and pose as customers (I don’t support that).
  • WP Engine – also not what they used to be, expensive and not even fast anymore.
  • SiteGround – had one of the slowest TTFBs reported by Backlinko. Also one of the slowest in my speed test just above HostGator. Went downhill recently in many ways (slow TTFB, CPU limits, reduced support, price increases, renewals, Site Tools). Search “SiteGround” in FB Groups and you will see many complaints and people moving away.

Affiliate Disclaimer – if you sign up for Cloudways using my affiliate link or use code OMM25, watch this video. I try to give solid recommendations based on Facebook Group trends, unbiased polls, migration results, and constant research/testing. I also donate to charity ($6,000 to GoFundMe so far) and your support would honestly help.

 

Frequently Asked Questions

What causes CPU issues?

This simply means your hosting plan can't handle your website and plugin's resource consumption. The only way to fix this is to increase CPU (upgrade your hosting plan) or optimize your website and plugins to consume less CPU so they fall within your limits.

Is GoDaddy the problem?

GoDaddy was rated very poorly in Facebook Groups and are one of the least recommended hosts among the WordPress community. Their domains are fine, but their servers are overcrowded and slow. This is well-known among the hosting community.

What are 3 easy ways to fix CPU issues?

Upgrade the a higher PHP version inside your GoDaddy account, remove any slow loading plugins, and finally, move away from GoDaddy.

Will upgrading my plan help?

It might, but there have also been many reports of GoDaddy customers still getting CPU issues when they upgrade to a more expensive hosting plan. I recommend optimizing your website, then only upgrade plans if you still get errors. Or explore other hosting options.

How do I find my slowest plugins?

Run your site through GTmetrix and look at the Waterfall tab to see which of your plugins take longest to load. You can also use the Query Monitor plugin to find slow plugins, and finally, avoid my list of 65+ common slow plugins.

I hope this tutorial was helpful! Drop me a line if you have questions.
