HeartCore is classified as a dynamic CMS. The biggest advantage of using a dynamic CMS is that it allows effective management of, for example, a huge amount of contents, multi-device support and social media integration. However it generates each web page every time it is accessed, which is always a cause for concern about performance issues. Of course, it cannot even compete with a static system which only loads html files. As for website traffic, however, its performance is more than enough. Especially since v8.1.3, performance has been drastically improved by cache implementation (in Enterprise or upper edition).
Please consider adopting HeartCore to realize a dynamic operation of your website with extremely high performance.
Compared to other dynamic CMSs, HeartCore is better at performance but it is still difficult to maximize its potential without tuning.
