Hello, At http://www.pricearchive.org we use Highcharts to show price history charts for millions of goods. Everything works fine as long as the product has little data. When a product has a lot of data, it still works well but we have an issue with DOM size according to PageSpeed Insights. You can see this page as an example - https://developers.google.com/speed/pagespeed/insights/?hl=en&url=https%3A%2F%2Fwww.pricearchive.org%2Faliexpress.com%2Fitem%2F32829165465. This is the analysis for this item - https://www.pricearchive.org/aliexpress.com/item/32829165465.
In the Diagnostics section see the second recommendation 'Avoid an excessive DOM size' - 2,599 nodes. 'Browser engineers recommend pages contain fewer than ~1,500 DOM nodes. The sweet spot is a tree depth < 32 elements and fewer than 60 children/parent element. A large DOM can increase memory usage, cause longer style calculations, and produce costly layout reflows.' For the same reason, two more issues appear.
Every day adds new data and the number of DOM nodes is constantly increasing. Is there a way to get rid of these issues?
