We received the following customer feedback

I noticed the blogs associated with author Abhi Rele populated very slowly on the page, to the point that I originally thought they were missing.

The problem is:

• We are progressively going through the index to look for blogs that match the author, but these could be very far in the past.
• Even though we chunk the rendering to 20 cards at a time, it could still be that an author only has blogs in 2017 and we need to keep downloading until we get there.
• This is not a problem after the index information gets cached in the CDN and in the local browser, but cold loads can show a load delay even of a few seconds
• The lighthouse score is 100, so any fix should still keep it
• Too small chunks could create a different user experience problem if we go that route

Possible solutions:

• Having a way to compute in xcel the list of blogs for others (ideal)
• Introducing a loading spinner to help with the user experience, but don't really fix the performance and might upset LHS which doesn't really like animations (might see it as CLS)
• Splitting the blogs sheet per language (blogs-en-US, blogs-en-UK, etc.) to make the search space smaller, but requires a bigger some refactoring, as there are multiple blocks using that sheet. The search space will keep growing as the new blogs are being published, but at a slower rate.
• Hybrid solution between everything above
