Why cacheroot website to the level of whole html pages?
Well, I imagine, the attendance of 100 people per minute, even though I hardly imagine that the majority of sites.
So, even one page, in rukozhopyh coders doing well, for example, 20-30 queries to the database. Is the resource consumption of real-time, outweigh the cost of maintaining the cache and change tracking? It is a relic of past years or really working scheme? Again, it's not about over the highly visited sites, although those would have issues.
Is done for immediate response and for search engine optimization

1. In order to speed up the page load time. In WordPress, for example, I remember from the box is 45 queries to the database about. After installing the plugin from caching the page load speed is 2-3 times faster.
2. To save on servers. If the server is not very good, and the money for good power there.
3. To optimize high-load applications - but is used there object caching.
