The diagram shows the current total size of all JavaScript files against the prospective JavaScript size after its minification and compression. It is highly recommended that all JavaScript files should be compressed and minified as it can save up to 300.5 kB or 67% of the original size.

    • Original 104.9 kB
    • After minification 86.1 kB
    • After compression 21.2 kB

Visitor World Map

Country of origin for 72.5% of all visits is Germany. It lies approximately 3860 miles away from the server location (India) 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 Germany or just closer to the user base.
