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.

With more standardised FOUT/FOIT behaviour from browser vendors, to the newer font-display specification, performance—and therefore the user—seems to have been finally been put front-and-centre. On this site, in which performance is the only name of the game, I forgo web fonts entirely, opting instead to make use of the visitor’s system font.

Its raison d’être is to cache result rows from a plan subtree, then replay those rows on subsequent iterations if any correlated loop parameters are unchanged. For more background on these performance spools see my prior article. Spools are the least costly way to cache partial results. Demo 1: Inaccurate Rewinds.

Performance spools are lazy spools added by the optimizer to reduce the estimated cost of the inner side of nested loops joins.

While an eager index spool may only appear on the inner side of an nested loops apply , it is not a "performance spool". The next code example shows a DMV query that is successfully converted from a join to an apply. These are extremely rare in my experience, so I am not going to provide demos for them.

Due to strong templating support, a website managed by SSG can be truly modular.

A component is simply a set of pieces of HTML, JavaScript and CSS code put all together to create an autonomous entity. In conclusion, a schema-based API such as GraphQL and a component-based API such as PoP are similarly good concerning performance, and superior to a resource-based API such as REST. So GraphQL is not DRY.
