Unoptimized content could also be one of the reasons why your WordPress website is not performing as per your expectations. Many factors affect the speed of your WordPress website; some of them are: Your web host Server-side optimizations (PHP version, compression, caching, etc.) So let's discuss the process one step at a time.

Font loading has long been a bugbear of web performance, and there really are no good choices here. The thinking here was that it was better for performance to display the text as quickly as you can , even if it’s in the fallback font, and then to swap the font in when it finally downloads.

This was convenient for the demos but repeatable read isolation isn’t common in everyday use. Rows qualifying for the update must continue to qualify until the change is performed and committed. Using lock classes is better for resource usage, concurrency, and performance than internally escalating to repeatable read would be.
