Windows 10 is faster than Windows 7:
>Older versions of Windows have a larger performance impact because Windows 7 and Windows 8 have more user-kernel transitions because of legacy design decisions, such as all font rendering taking place in the kernel.

- tomsmeding 9y agoFont rendering taking place in the kernel does indeed look quite like a legacy design decision.
- cremno 9y agoIt's also kinda ironic because improved performance was the reason behind that decision.
- mehrdadn 9y agoTo be honest it might still have better performance if/when they add more mitigations for more security vulnerabilities. It seems like an anomaly right now since they're only addressing Meltdown/Spectre, but the core issues (no pun intended) are fundamentally there.
