Page optimization

  • HTML 26.9 kB
    Images 314.1 kB
    Javascripts 248.6 kB
    CSS 104.1 kB

    • Original 26.9 kB
    • After minification 26.0 kB
    • After compression 7.2 kB

Possible request optimization













Normal 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.
