When considering the HubSpot Content Optimization System (COS) for your high-traffic site, you will likely want to know how the COS handles significant volumes of traffic. The HubSpot COS is more than capable of providing a fast experience while serving millions of pageviews. Here are some things to keep in mind when planning to host a high-traffic site on HubSpot:

Maximum Load
The COS is currently set up to handle around 1,000 pageviews per second to a website. This means your site is capable of handling 3.6 million pageviews an hour or about 86 million pageviews a day when hosted on the COS. It would be extremely difficult for a singular event to generate enough legitimate traffic to adversely affect the loading of a COS site.

Requesting Load Tests
If you know you’re going to have an event that would drive an unusually large surge of traffic to your site, it’s best to be safe and let your Customer Success Manager know ahead of time so HubSpot can plan for it. This way there will be no surprises and your moment in the spotlight will be unfettered by site problems.

Please note: performing load tests on your own is against our Terms of Service and has the potential to harm multiple customer sites in addition to yours. Again, whenever you’re thinking about performing one of these tests, please let your Customer Success Manager know and they'll be happy to talk through any potential issues.

Ensuring a Smoother Load Experience
If you’re expecting even a modest traffic spike, it’s a good idea to work with your web developer/team to make sure the website loads quickly and is accessible no matter what situation you’re in. Luckily, because the COS handles the server configurations you would likely need to do on other content management systems, most of the heavy lifting is done for you. The only thing you should do when planning for a speedy website is avoid overly large images and excessive use of videos and .js snippets. Check out Google Page Speed for more guidelines to help speed up your site.

Finally, if you know the site you’ll be hosting on the COS is going to have a consistently high volume of traffic (more than one million pageviews a day), let your Customer Success Manager know in advance so HubSpot can be prepared to host your site in the best manner.
