Shrinking the Website and Still Fighting the Performance Scores

April 16, 2021

A practical optimization day: breakfast, more minimization, Lighthouse and WebPageTest confusion, GTmetrix and Dare Boost checks, image-format decisions, SLT delays, and the sinking realization that even after making the site smaller, the performance numbers still refuse to behave cleanly.

Very strangely, I found out that my efforts did not really result in improvements:

Very, very strange.

So, performance plunged from initial 33 to 21, then up to 25 and then 28.

Crazy.

I mean, at 6:32 PM, I had already removed many elements, so it is very strange.

I dunno. Maybe, I have work to do or I need to use a CDN service or something--

Very, very strange, I am 'in over my head' as this is not my area of expertise, though I am learning.

I have a gut feeling, I have improved things because the homepage was minimalized.
