--- Comment #1 from Alexander Kornienko <alexfh at google.com> ---
Well, if you want to run only clang-analyzer-llvm.Conventions, you should
specify -checks=-*,clang-analyzer-llvm.Conventions. With just one check,
clang-tidy analyzes this file on my machine in ~39s. Just parsing of this file
takes ~3s, so the rest time is spent inside the static analyzer.

Static analyzer folks may want to take a look at why analyzing this file takes
so much time.
