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 168.0 kB or 67% of the original size.

    • Original 35.9 kB
    • After minification 28.8 kB

As for redirects, our browser was forwarded to before it reached this domain.

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.
