Page optimization

  • HTML 120.2 kB
    Images 803.5 kB
    Javascripts 1.1 MB
    CSS 209.8 kB

    In fact, the total size of main page is 2.3 MB. This result falls beyond the top 1M of websites and identifies a large and not optimized web page that may take ages to load. 80% of websites need less resources to load and that’s why Accessify’s recommendations for optimization and resource minification can be helpful for this project. Javascripts take 1.1 MB which makes up the majority of the site volume.

    • Original 120.2 kB
    • After minification 118.2 kB
    • After compression 29.1 kB

    HTML optimization

    HTML content can be minified and compressed by a website’s server. The most efficient way is to compress content using GZIP which reduces data amount travelling through the network between server and browser. HTML code on this page is well minified. It is highly recommended that content of this web page should be compressed using GZIP, as it can save up to 91.1 kB or 76% of the original size.

    • Original 803.5 kB
    • After optimization 768.4 kB

    Image optimization

    Image size optimization can help to speed up a website loading time. The chart above shows the difference between the size before and after optimization. Petrobras images are well optimized though.

    • Original 1.1 MB
    • After minification 1.0 MB
    • After compression 348.5 kB

    JavaScript optimization

    It’s better to minify JavaScript in order to improve website performance. 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 775.9 kB or 69% of the original size.

    • Original 209.8 kB
    • After minification 148.2 kB
    • After compression 25.0 kB

Possible request optimization













Normal result


As for redirects, our browser reached this domain in two steps. The first redirect led to, then it was forwarded to, and finally we managed to open this domain. We strongly recommend that the redirects should be reduced, as the more redirects a site has, the slower it loads.

IP address uses IP address which is currently shared with 1 other domain. 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 90.2% of all visits is Brazil. It lies approximately 5710 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 Brazil or just closer to the user base.
