Possible request optimization











Good result

IP address uses IP address which is currently shared with 4 other domains. The more sites share the same IP address, the higher the host server’s workload is. It is strongly recommended that the host server should be changed or the hosting provider should be requested to give a different (separate) IP address for this domain.

Visitor World Map

Country of origin for 80% of all visits is Canada. It lies approximately 5150 miles away from the server location (United States) 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 page load time for the majority of users is moving the server to Canada or just closer to the user base.
