Re: [android-building] verbose: *kati*: slow included makefiles (1037.829698): art/Android.mk

['Dan Willemsen' via Android Building]

So that time was mostly spent initializing the find emulator:

verbose: *kati*: init find emulator time: 1311.781312

What that's doing is walking through your source tree and building up a
data structure to more efficiently (normally!) run `find` commands. This
can become very slow if you've added a symlink into your source tree
pointing to elsewhere on your filesystem (or a network filesystem). We've
also had reports that this can get very slow when you have a lot of output
trees under your source tree (being discussed in
https://github.com/google/kati/issues/184), but 20 minutes seems excessive
for that -- it claims that there are ~3M nodes in the cache:

verbose: *kati*: 3071468 find nodes

One of my AOSP trees (after removing out/) is closer to 1M nodes (~2s), and
after a hikey960 build it has ~1.5M nodes (3.4s).
