Speedy performance of any blog is very important for sales, user subscriptions, search engine ranking and others. Performance optimization plays an important role in the improvement of Pagerank as well.
WordPress pages can be slow because of the large number of files and database calls the system must process while the visitor waits to see it. By saving these dynamic pages as static HTML after they are viewed, subsequent page views are served much faster.
