This can make "$ bitbake-layers show-recipes" save about 60% time (14min -> 6min) in my build (more than 3000 recipes) The command "bitbake-layers show-recipes" calls bb.utils.get_file_layer() with each recipe, and get_file_layer() compare the file with each item in BBFILES which makes it very time consuming when there are a lot of recipes and items in BBFILES. So use BBFILES_PRIORITIZED and exit when file is matched, it doesn't make sense to go on the loop when file is matched. And use fnmatchcase to replace of fnmatch since the comparison should be case-sensitive.

Bitbake
BitBake is a generic task execution engine that allows shell and Python tasks to be run efficiently and in parallel while working within complex inter-task dependency constraints. One of BitBake's main users, OpenEmbedded, takes this core and builds embedded Linux software stacks using a task-oriented approach.
For information about Bitbake, see the OpenEmbedded website: http://www.openembedded.org/
Bitbake plain documentation can be found under the doc directory or its integrated html version at the Yocto Project website: http://yoctoproject.org/documentation
Contributing
Please refer to http://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded for guidelines on how to submit patches, just note that the latter documentation is intended for OpenEmbedded (and its core) not bitbake patches (bitbake-devel@lists.openembedded.org) but in general main guidelines apply. Once the commit(s) have been created, the way to send the patch is through git-send-email. For example, to send the last commit (HEAD) on current branch, type:
git send-email -M -1 --to bitbake-devel@lists.openembedded.org
