Windows 10 security feature causes huge Chromium performance issues: Fix coming
Summary
Microsoft is working on a fix for what browser maker Vivaldi and a Google researcher say are major performance issues caused to Chromium. Dawson found that disabling CFG, which isnt strictly necessary in a test environment and shouldnt be performed in the real world, resolved the issue. Mehmet Iyigun, a development manager on the Windows and Azure kernel team, confirmed in late April that Microsoft had investigated the root cause and built a fix that would roll out "in a couple of weeks". The second bit of good news is that its end users probably wouldnt experience the same performance issues that a test environment reveals, according to Pettersen. "It could be that this issue affects normal browser usage, too, since both Chrome and Vivaldi start new processes for each tab, but as much of the actual code is located in DLLs shared among the processes, and the Windows CFG configuration is reused for DLLs, it might not be as noticeable in normal use," wrote Pettersen.
