The previous code add all BBFILE_COLLECTIONS/recipes*/*/*.bbappend to BBFILES, which causes the parsing very slow when there are many layers, e.g., I have 87 layers:
* Before: $ rm -fr tmp-glibc/ cache; time bitbake -p real 0m45.173s user 0m0.560s sys 0m0.060s * After: $ rm -fr tmp-glibc/ cache; time bitbake -p real 0m25.542s user 0m0.572s sys 0m0.040s It cost 20s which isn't worth (The host has 128 threads, it should cost more time on less power host), only set BBFILES according to known layers (currently: meta-python, networking-layer and virtualization-layer) can fix the problem.
