Summary

Microsoft engineers have documented a "performance tax" on iOS browsers caused by Apple's requirement that all iOS browsers use the WebKit engine (the same engine powering Safari). According to their analysis, this restriction results in a 28.6% performance hit, meaning rival rendering engines could make pages load almost 30% faster on iPhones. The article compares this to Apple's well-known 30% App Store commission, framing it as another form of Apple's restrictive control over iOS.
