Any chance some of this could be due to sidechannel exploit mitigation? The timing seems about right.

- moistbar 5y ago1809 is the first build that shipped with the mitigations, so that explains why there are a lot of performance problems around that time.
- Arcuru 5y agoAlmost certainly. Several of the worst benchmarks (Win32 App launch, UWP App launch, and Explorer stress test) all start increasing in the 2018 H1/H2 releases. That matches the timeline for the Spectre/Meltdown fixes, and those are the benchmarks that I'd expect would be most effected. 17134 = 2018 H1 (1803) 17763 = 2018 H2 (1809)
