Hosting #82

Disable some web server access logs

By limiting the number of events registered in the application’s log, we avoid writing to the disk, which minimizes CPU consumption and the storage space needed.

Hosting #75

Use a CDN

Some files such as the JavaScript libraries, CSS style sheets and images consume lots of network resources because there are lots of them and they are usually small. CDNs (Content Delivery Network) are thus recommended as they bring the files physically closer to users, saving large amounts of bandwidth and improving response time.
