Scalability and Performance

Kentico CMS performs extremely well on a very standard hardware configuration. Still, if you need more power and scaling up (adding more CPU and memory) isn't enough, you can easily scale out and deploy Kentico CMS in a webfarm. Kentico runs in a standard Windows Server web farm environment and it has built-in mechanisms for automatic synchronization of files and in-memory objects across servers. Based on our performance tests, adding a second web server doubles the overall performance.

If the database server becomes a bottleneck, Kentico CMS supports SQL Server Merge Replication which means you can also scale out your database servers. It means you can achieve virtually unlimited scalability with Kentico CMS.

Standard Kentico CMS installation was tested for management of 100,000 items (pages, articles, news, etc.) in the content repository and 10,000,000 users in the database. Still, we have clients who manage milions of content items using project-specific configuration of Kentico CMS.

We have created a Performance Test Report that shows you how Kentico CMS performs on various configurations.

Some of the key findings:

• Kentico CMS can handle more than 12,000 requests per second on a single standard web server
• Adding an additional web farm server doubles the overall performance
• Kentico CMS performs equally well with 300 as with 100,000 documents when at least webpart caching is used.
