Country of origin for 16.7% of all visits is Peru. It lies approximately 6080 miles away from the server location (Spain) and such a long distance can negatively affect website speed, as it takes some time for data to travel back and forth between those places. That’s why one of the best ways to speed up Dfa.upc.es page load time for the majority of users is moving the server to Peru or just closer to the user base.
