[llvm-dev] monorepo: bad performance when using gitk / git log

[Alexander Benikowski via llvm-dev]

I use GitExtension and have no performance issues. However i noticed GitExt
will only visualize the last 3 years on the overview. When looking at a
specific files history or blame, it will show the entire history of it(last
10 years)
