Performance scores are likely not going to be much higher than 70, and usually are around 30-40.
In terms of why that text has the issue, it would likely be due to the plugin you use to make it animate, or if not a plugin, just the animate on page load.
To fix, you can change the trigger from ‘when page is loaded’ to a conditional trigger for when page is loaded entirely is yes, which would only start the animation after the entire page is loaded, which should have a positive impact on page load score. If that doesn’t work, test by deleting the text element altogether and see what you performance score is then.
