WP default themes 2010-2014: performance going down

Although it is easy to download and install free or “premium” themes, WordPress does come with a default theme that is updated yearly. Last year I did performance tests of Twenty Twelve and there were some performance-issues, which led me to create a cleary faster child theme (2012.FFWD). But how does Twenty Thirteen fare, you [...]

2012.FFWD; high performance Twenty Twelve child theme

Twenty Twelve is beautiful but slow, so I created 2012.FFWD. This Twenty Twelve child theme looks pretty much the same as the original, but comes with the following performance-boosting changes under the hood: no webfont downloaded: loading fonts slow sites down, always. Fallback-fonts as defined in Twenty Twelve (Arial, Helvetica, Sans-Serif) are used instead. minimized [...]

lyteShare.js high-performance social widget for your sharing pleasure

Based on last week’s performance analysis of popular sharing-services (AddThis, ShareThis and Lockerz/AddToAny) I decided to continue working on my high-performance & privacy-respecting but rather ad-hoc lyteShare alternative.

I’m not a fan [...]

Speed matters: re-evaluating WP YouTube Lyte’s performance

So stupid me made a (smallish) mistake when working on 1.1.0, which caused WP YouTube Lyte (rapidly approaching 80.000 downloads, thanks guys & girls) to load immediately instead of waiting for the “document loaded” event (lazy loading). That got fixed in 1.1.2 (which also loads the CSS differently, resulting in 1 file less to request), [...]

Website performance: impact of web fonts

Although it was possible to embed fonts in web pages even during the dark ages of the internet, 2010 was the year when the pieces of the web typography puzzle really fell into place, Designers, Marketeers and especially “brand identity guards” are ecstatic about this evolution. But there’s little to be found on the performance [...]
