Apple's WebKit performance tax leaves iOS browsers stuck in the slow lane, says Microsoft

Rival rendering engines could make pages load almost 30% faster on iPhones, Redmond claims

Why this matters
Why now

The European Union's Digital Markets Act (DMA) is forcing Apple to open up its iOS ecosystem, leading to direct competition and public criticism from rivals such as Microsoft regarding previously restrictive practices.

Why it’s important

This highlights the ongoing impact of regulatory pressure on entrenched tech giants and the potential for new market dynamics in mobile browsing performance and user experience.

What changes

Users on iOS theoretically gain access to faster browsing experiences through alternative browser engines, and Apple's historical control over web rendering on its platform is diminished.

Winners
  • · Microsoft (browser division)
  • · Google (Chrome)
  • · Mozilla (Firefox)
  • · iOS users
Losers
  • · Apple (Webkit team)
  • · Safari browser
Second-order effects
Direct

Third-party iOS browsers using alternative engines will likely see increased adoption due to performance improvements.

Second

Apple may be forced to significantly improve WebKit performance to remain competitive, or face user migration to rival browsers.

Third

Increased competition on iOS could lead to innovation in mobile browser features and performance across the entire mobile ecosystem, potentially impacting Android browser development as well.
