Page optimization

  • HTML 14.7 kB
    Images 33.9 kB
    Javascripts 938 B
    CSS 2.9 kB

    In fact, the total size of main page is 52.5 kB. This result falls within a vast category (top 1 000 000) of heavyweight, probably not optimized, and thus slow loading web pages. Only 5% of websites need less resources to load. Images take 33.9 kB which makes up the majority of the site volume.

    • Original 14.7 kB
    • After minification 12.5 kB
    • After compression 4.7 kB

    • Original 938 B
    • After minification 827 B
    • After compression 439 B

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 499 B or 53% of the original size.

    • Original 2.9 kB
    • After minification 2.2 kB

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

IP address uses IP address which is currently shared with 3 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.
