[PATCH] D121712: [clangd] Track time spent in filesystem ops during preamble builds

[Trass3r via Phabricator via cfe-commits]

Trass3r added a comment.

Hmm just a few curious questions from the sidelines.
Why a "custom system" instead of something -ftime-trace based?
How much overhead does this introduce, esp. for normal use-cases?
What's the gain? The information is very coarse and general-purpose system profiling tools should give you much better information regarding file system perf.
